Light guide plate and display apparatus including the same

摘要

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.

主权项

1. A display apparatus comprising:
at least one light source outputting light; a light guide plate guiding the light; and a display panel receiving the light from the light guide plate, wherein the light guide plate comprises;
a light incident surface facing the light source and receiving the light;a light facing surface reflecting the light toward the light incident surface, the light facing surface having an arc shape;a top surface connected with the light incident surface and the light facing surface, the top surface outputting the light, wherein the top surface comprises a flat surface; andconnection surfaces provided at both sides of the light incident surface to connect the light incident surface with the light facing surface, wherein the connection surfaces are substantially perpendicular to the top surface,wherein each of the connection surfaces comprises at least two absorption surfaces and at least one reflective surface provided between the two adjacent absorption surfaces, the reflective surface reflecting the light, and each of the connection surfaces has a stepped surface.
