Abstract: A light guide plate includes a light incident surface, a light facing surface facing the light incident surface, a connection surface connecting the light incident surface with the light facing surface, and a top surface connected with the light incident surface, the light facing surface, and the connection surface. The light incident surface receives light from a light source, the light facing surface reflects light, and the top surface outputs light toward a display panel. The connection surface includes at least two absorption surfaces parallel to a straight line linking a center of an arc with an end of the light incident surface and at least one reflective surface interposed the two adjacent absorption surfaces to reflect the light.

Abstract: A backlight assembly includes; a light source including a light emitting surface through which a light exits and an optical member including a first surface disposed adjacent to the light source and a second surface disposed substantially opposite to the first surface, wherein the optical member covers the light source and guides the light therethrough, wherein the optical member includes; an incident surface to which the light is incident, the incident surface being connected with the first surface corresponding to the light source, an optical pattern disposed on the second surface and corresponding to the light source, the optical pattern reflecting a first light of the light incident through the incident surface through total internal reflection and a light guide pattern disposed on the first surface, wherein the light guide pattern directs the reflected first light to an exterior of the optical member.

Abstract: A display apparatus includes a light source and a light guide plate including a light incident surface facing the light source and which receive the light, an opposite surface opposite to the light incident surface and which reflects the light and has an arc shape, connection surfaces at opposing sides of the light incident surface and which connect the light incident surface and the opposite surface, an upper surface connected to the light incident surface, the opposite surface and the connection surfaces and which outputs the light, and a lower surface opposite to the upper surface. The light incident surface of the light guide plate includes a first surface extending in a predetermined direction, and second surfaces inclined from the first surface in an area corresponding to the light source such that an optical recess having a polygonal pyramid shape is defined by the second surfaces.

Abstract: A light source lens includes a refraction surface having a concave portion proximate to a central axis of a light source lens. The central axis passes through a light source that is coupled to the light source lens. An angular distribution function F(??) of a first light emitted from the light source and refracted at the refraction surface at least approximately satisfies F ? ( ? ? ) ? 1 cos 3 ? ( ? ? ) , where ?? is a latitude angle of the first light refracted at the refraction surface with respect to the central axis. The lens refracts a light emitted from the light source so that the resulting luminance at the upper area of the light source is more uniform.
