1. A curved display device comprising:
- a curved backlight unit comprising;
a light source which generates light; and
a curved light guide plate which receives the light from the light source, the curved light guide plate defining;
a light incident surface which faces the light source, the light incident surface curved along a first direction when viewed from the light source; and
an opposite surface facing the light incident surface in a second direction crossing the first direction,wherein a thickness of the curved light guide plate decreases along the second direction from the curved light incident surface to the opposite surface;
a curved display panel which is disposed on the curved backlight unit and receives the light generated by the curved backlight unit to display an image; and
a curved bottom chassis on which the curved backlight unit and the curved display panel are supported, the curved bottom chassis curved in the first direction along which the light incident surface of the curved light guide plate is curved, wherein a thickness of the curved bottom chassis decreases along the second direction from the curved light incident surface of the curved light guide plate to the opposite surface thereof.

Abstract
A curved display device includes a backlight unit which generates light and a display panel which receives the generated light from the backlight unit. The backlight unit includes a light guide plate and is curved. The display panel is disposed on the curved backlight unit and is curved. The curved light guide plate defines a light incident surface thereof and an opposite surface. The light incident surface receives the light generated by the curved backlight unit. The opposite surface faces the light incident surface. A thickness of the curved light guide plate decreases from the light incident surface to the opposite surface.
