Abstract

A liquid crystal display device includes: a light guide plate that includes upper, lower and side surfaces; a light emitting element disposed to face an edge surface that is a part of the side surfaces; a reflection sheet that is bent to face the lower surface of the light guide plate and parts of the side surfaces thereof except for the edge surface; and an adhesive material disposed on the reflection sheet in a planar shape of dots or stripes and attaches the reflection sheet to the light guide plate. The lower surface of the light guide plate includes concaves and convexes formed to cause light that advances in the light guide plate to be reflected inside and to advance toward the upper surface. The thickness of the adhesive material is smaller than a maximum value of a height difference of the concaves and convexes.
