摘要： 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.

摘要： A light guide plate includes at least one incident surface into which light is incident, an exit surface at least one end of which is connected the incident surface and through which the light is output, an opposite surface spaced apart from the exit surface and opposing the exit surface, and a plurality of reflective patterns extending from the exit surface toward the opposite surface. When a direction from the exit surface to the opposite surface is referred to as a first direction, a direction perpendicular to the incident surface is referred to as a second direction, and a direction parallel to the incident surface and perpendicular to the first direction is referred to as a third direction, a length of each reflective pattern in the first direction is smaller than a distance between the exit surface and the opposite surface, and a length of each reflective pattern in the second direction is larger than a length of each reflective pattern in the third direction.
摘要翻译：导光板包括至少一个光入射的入射表面，其出射表面的至少一端连接入射表面并输出光，与出射表面间隔开的相反表面，出射表面和从出射表面延伸到相对表面的多个反射图案。当从出射表面到相对表面的方向被称为第一方向时，将与入射表面垂直的方向称为第二方向，并且参考与入射表面平行且垂直于第一方向的方向作为第三方向，第一方向上的每个反射图案的长度小于出射表面和相对表面之间的距离，并且每个反射图案在第二方向上的长度大于每个反射图案的长度在第三个方向。
