Abstract
According to one embodiment, a liquid crystal display device includes a first display panel, a backlight and a second display panel. The first display panel includes a display area for displaying an image. The second display panel is provided between the first display panel and the backlight and controls brightness of the image displayed on the first display panel. The first display panel and the second display panel both include a liquid crystal layer. A first refractive index of a member provided between the liquid crystal layer of the second display panel and the liquid crystal layer of the first display panel is higher than a second refractive index of a member provided above the liquid crystal layer of the first display panel.
Claims8
A liquid crystal display device comprising:
- a first display panel that includes a display area for displaying an image;
- a backlight that is provided on an opposite side of a display surface of the first display panel;
- and
- a second display panel that is provided between the first display panel and the backlight and controls brightness of the image displayed on the first display panel, wherein
- the first display panel and the second display panel both include a liquid crystal layer, and
- a first refractive index of a member provided between the liquid crystal layer of the second display panel and the liquid crystal layer of the first display panel is higher than a second refractive index of a member provided above the liquid crystal layer of the first display panel.
A liquid crystal display device comprising:
- a first display panel that includes a first polarizer and a second polarizer;
- a second display panel that includes a third polarizer and a fourth polarizer;
- and
- an adhesive layer that is disposed between the first display panel and the second display panel, wherein
- the first display panel is provided on the second display panel,
- the first polarizer is located between the second polarizer and the adhesive layer,
- the fourth polarizer is located between the adhesive layer and the third polarizer, and
- a refractive index of at least one member of the first polarizer, the adhesive layer, and the fourth polarizer is higher than a refractive index of the second polarizer.
