A display apparatus includes a liquid crystal display panel and an illuminator disposed at the back of the panel for emitting at least two illumination lights having directivities in different directions toward the panel. The illuminator includes a light guide plate made of transparent material whose one end surface serves as a light entrance end surface, whose one plate surface serves as a light exit surface, and whose other plate surface serves as a light direction changing surface for changing the advancing direction of light entering from the light entrance end surface. The light direction changing surface has a plurality of circular-arcing slanted surfaces shaped into semicircles formed on concentric circles centered at the center of the longer dimension of the light entrance end surface. Light emitting elements are disposed on the light entrance end surface at two positions on left and right sides of the center equidistantly apart therefrom.
