Liquid crystal display device

A liquid crystal display device comprising:

• a liquid crystal panel;
• a backlight irradiating the liquid crystal panel with light;
• a light guide plate being disposed in the backlight;
• and
• plural light emitting diodes being arranged along a side surface of the light guide plate,
• wherein the light guide plate includes a light exiting surface from which the light is emitted and a bottom surface that faces the light exiting surface,
• grooves that are disposed such that the light is emitted from the light guide plate are disposed in the bottom surface of the light guide plate,
• a reflection sheet is disposed along the bottom surface of the light guide plate, the reflection sheet includes a multilayer film,
• the multilayer film includes a plurality of laminated films having different refractive indexes,
• projections that prevent tight adhesion between the light guide plate and the reflection sheet are disposed in the vicinity of the light emitting diodes of the light guide plate,
• a width of the projection is smaller than a width of each of the grooves,
• each of the grooves extends along a same direction as the arranged light emitting diodes, and
• a plurality of projections are arranged so as to be dispersed between the light emitting diodes and the grooves.

A liquid crystal display device comprising:

• a liquid crystal panel;
• and
• a planar illuminating device irradiating the liquid crystal panel with light, wherein
• a light guide plate that includes a light exiting surface and a bottom surface that faces the light exiting surface is disposed in the planar illuminating device,
• a side surface that intersects the light exiting surface or the bottom surface is disposed in the light guide plate,
• plural LEDs are disposed along a first side surface of the light guide plate,
• light of the LEDs is made incident from the first side surface,
• the first side surface is configured as light incident surfaces of the light guide plate,
• the light that has been made incident on the light guide plate is directed toward the light exiting surface by a scattering member disposed on the bottom surface of the light guide plate and is emitted from the light exiting surface,
• a reflection sheet that includes a multilayer film is disposed on the bottom surface side of the light guide plate,
• the multilayer film includes a plurality of laminated films having different refractive indexes,
• spacing members are disposed between the reflection sheet and the light guide plate so as to define an air gap between the bottom surface and the reflection sheet,
• a width of each spacing member is smaller than a width of each of the scattering member,
• the scattering member extends along a same direction as the LEDs are disposed, and
• a plurality of spacing members are arranged so as to be dispersed between the LEDs and the scattering member.
