1. A liquid crystal display device comprising:
a liquid crystal display panel; a light guide plate that includes an upper surface, a lower surface and side surfaces, in which the upper surface is disposed to face the liquid crystal display panel; a light emitting element that is disposed to face an edge surface that is a part of the side surfaces of the light guide plate; 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 adhesive materials that are disposed on the reflection sheet in planar shapes of a plurality of dots to attach the reflection sheet to the light guide plate, each of the plurality of dots having a dome shape by surface tension, wherein the lower surface of the light guide plate includes depressions and protrusions formed to cause light that advances in the light guide plate to be reflected inside and to advance toward the upper surface, wherein each of the protrusions has a top touching the reflection sheet, wherein each of the depressions has a bottom facing a corresponding one of the adhesive materials with a distance therebetween, wherein some of the plurality of dots are disposed in the depressions and do not contact the light guide plate, and wherein each of the adhesive materials has a thickness smaller than a maximum value of a height difference of the depressions and protrusions, the distance between the bottom of each of the depressions and the corresponding one of the adhesive materials being smaller than the maximum value of the height difference. |
