摘要： A display apparatus includes a display panel, a plurality of spaced apart point light sources outputting light and each having an orientation angle greater than or equal to about 50° and less than about 90°, and an optical plate interposed between the display panel and the point light sources. The optical plate has a base comprising front and rear surfaces and a plurality of convex sections formed on the front surface of the base. Each convex section has a cross section perpendicular to the front surface in which the cross section has a form of a segment of an ellipse including an arc of an ellipse and a chord linking both ends of the arc while satisfying an equation, 1.0

摘要： A display apparatus includes a light guide plate, a light source unit and a display panel. The light guide plate includes an incident surface, an exit surface and an opposite surface opposite to the exit surface and guides a light incident into the incident surface toward the exit surface. The light source unit includes a light source which generates light and is disposed adjacent to the incident and has an emitting surface inclined with respect to the incident surface. An extension line of a normal line of the emitting surface passes through the opposite surface, and the light is incident into the incident surface while being inclined toward the opposite surface. The display panel displays an image by receiving the light emitted from the exit surface.
