摘要： A liquid crystal display device has a thin structure with a backlight device appropriate for illuminating a liquid crystal panel where there is no area in band form where the brightness is inconsistent. The size of the diffusion plate that forms the optical sheet of the backlight device is made smaller than the opening for illumination in the diffusion region, and the diffusion plate is not provided in the vicinity of the end portions of the opening for illumination in the configuration. In this configuration, the reflection properties are different in the vicinity of the end portions and as the center portion of the opening for illumination, and the brightness increases in the vicinity of the end portions of the backlight device, so that an area in band form where the brightness is inconsistent can be prevented from being created in the end portions of the display device.

摘要： The side surface of the light guide plate includes an incident surface which faces the light source unit in an opposed manner, and a fixing surface which is directed in the left-and-right direction orthogonal to the top-and-bottom direction which is the direction along which the light source unit and the incident surface each other in an opposed manner. An engaging portion which is engageable with a lower frame is formed on the fixing surface or an edge portion which forms the fixing surface. The engaging portion is configured to allow a change of a distance between the incident surface and the lower frame due to expansion or shrinkage of the light guide plate while restricting the movement of the light guide plate in the top-and-bottom direction.
