Display device
First Claim
1. A display device comprising:
- a liquid crystal display panel which is configured to sandwich a liquid crystal layer between a pair of transparent substrates which have electrodes for forming pixels on inner surfaces thereof;
an optical compensation sheet stacked body which is mounted on a back surface of the liquid crystal display panel;
a light guide plate which is mounted on a back surface of the optical compensation sheet stacked body, includes a light emitting surface which emits light by developing the light in a planar shape to a front surface which faces the liquid crystal display panel in an opposed manner, and includes a light incident surface which allows the light to be incident on a back surface which faces the light emitting surface in an opposed manner;
a first air layer which is interposed between the optical compensation sheet stacked body and the light emitting surface of the light guide plate;
a plurality of diffusion plates which are mounted on the light incident surface of the light guide plate;
a reflection sheet which is arranged to face the light incident surface of the light guide plate in an opposed manner;
an LED array which arranges an LED chip on a front surface of the reflection sheet; and
a second air layer which is interposed between the plurality of light diffusion plates and the LED array.

Abstract
A display device includes an optical compensation sheet stacked body mounted on a back surface of a liquid crystal display panel, and a light guide plate mounted on a back surface of the optical compensation sheet stacked body. A first air layer is interposed between the optical compensation sheet stacked body and the light emitting surface of the light guide plate, and a plurality of diffusion plates are mounted on the light incident surface of the light guide plate. A reflection sheet is arranged to face the light guide plate, and an array of an LED chips is provided on a front surface of the reflection sheet. A second air layer is interposed between the light diffusion plates and the LED array. Light from the LED chips having a plurality of colors is mixed and effective optical path length can be prolonged, whereby the least coupling loss is obtained.
