LCD displays include a substrate, spaced apart data lines on the substrate, and spaced apart gate lines on the substrate that intersect the spaced apart data lines to define an array of display elements. A display electrode and a reference electrode are provided in each display element. The display electrode includes display electrode fingers. The reference electrode includes reference electrode fingers that are spaced apart from the display electrode fingers. A reference electrode line extends across multiple display elements parallel to the reference electrode fingers, and electrically connects the reference electrodes in multiple display elements. Preferably, the display electrode fingers and the reference electrode fingers are symmetrically arranged about the reference electrode line in a display element. More preferably, the reference electrode line extends across a display element at the center thereof.
In order to realize the manufacture of a reflection type liquid crystal display in the same manufacture processes as those of a transmission type liquid crystal display, a photolithography mask capable of forming both a gate electrode 22 and a reflective layer 23, and a photolithography mask capable of forming only the gate electrode 22 are prepared, and by using either one of the masks, the reflection type liquid crystal display in which both the gate electrode 22 and the reflective layer 23 are formed on a transparent insulation substrate 21, and the transmission type liquid crystal display in which only the gate electrode 22 is formed are selectively manufactured.
A liquid crystal display device includes at least a common electrode line, a common electrode and a pixel electrode in each pixels, the common electrode line comprising a first common electrode line which extends in the extending direction of the gate lines and a second common electrode line which extends in the extending direction of the drain lines in the pixel region, the first common electrode line and the second common electrode line are spaced apart from each other by way of a first insulating film, the first common electrode line and the second common electrode line are connected via an opening portion formed in the first insulating film, and a second insulating film is formed over the opening portion.
A method for manufacturing a liquid crystal display panel includes preparing first and second substrates having an active region, forming a sealant along a periphery of the active region on at least one of the first and second substrates, dispersing a liquid crystal material on the at least one substrate, the liquid crystal material having a photo-reactant material, attaching the first and second substrates, and irradiating ultraviolet light on an entire surface of the at least one substrate.
A reflection type liquid crystal display provided with a reflective layer, a coplanar gate electrode, a color filter layer and a transparent pixel electrode and a manufacture method thereof. The reflection type liquid crystal display can be manufactured on the same manufacture line as that of a transmission type liquid crystal display. In order to realize this manufacture method, a photolithography mask capable of forming both a gate electrode and a reflective layer, and a photolithography mask capable of forming only the gate electrode are prepared, and by using either one of the masks, the reflection type liquid crystal display in which both the gate electrode and the reflective layer are formed on a transparent insulation substrate, and the transmission type liquid crystal display in which only the gate electrode is formed, are selectively manufactured.
The thin film transistor substrate increases an aperture ratio as well as prevents shorts between pixel electrodes by connecting drain electrodes of thin film transistors to storage electrodes to reduce the number of holes contacting the pixel electrodes. In the method of forming the thin film transistor substrate, drain electrode patterns are formed such that drain electrodes included in thin film transistors are electrically connected to storage electrodes included in storage capacitors. Accordingly, the number of holes contacting the pixel electrodes can be reduced so that an aperture ratio can be increased, or shorts between pixel electrodes can be prevented. Also, the drain electrode patterns are formed from the same conductive layer as the data lines supplying data signals to the thin film transistors, and a constant spacing between the two can be obtained to maintain a uniform parasitic capacitance therebetween and prevent deterioration of the data signal.
