Abstract
An irregular shape display having a hole according to the present disclosure may insert a cylinder-shaped guide member with the same material as that of a light guide plate within a hole to reduce a luminance difference between the front and the back of the hole, thereby improving a dark portion in the vicinity of the hole.Furthermore, the present disclosure may attach a reflection sheet to an upper portion of the guide member to block light leaked out between the light guide plate and the guide member.
