Abstract: An LCD device having light weight, slimness, and high luminance, includes: a display panel; a light source providing a light to the display panel; and a light guide plate including an upper surface facing the display panel, an opposing lower surface, a light incidence surface facing the light source, and a light opposing surface opposing the light incidence surface, the light guide plate including a prism area and a non-prism area on the lower surface. The light guide plate further includes a plurality of prisms arranged at the prism area along a first direction which is perpendicular to the light incidence surface, a linear portion disposed at the non-prism area and extending from the plurality of prisms, a first resin layer on the linear portion, and a second resin layer on the first resin layer, wherein the first resin layer is thinner than the second resin layer.

Abstract: A display apparatus includes a display panel which displays an image with light and a backlight unit which provides the light to the display panel. The backlight unit includes a first light source, a second light source and a circuit board. The circuit board includes in a top plan view, a first edge lengthwise extending parallel to a first direction and a second edge lengthwise extending parallel to a second direction crossing the first direction, and a sidewall portion extending from the bottom portion. In a third direction crossing the first and second directions, the sidewall portion includes first and second sidewall portions respectively extending from the first and second edges, and on which the first and second light sources are mounted.
