Abstract
The present invention prevents a moiré generated by the interference of two liquid crystal display panels in a display device capable of performing a three-dimensional display using two liquid crystal display panels. By arranging an upper lens array and a lower lens array between an upper liquid crystal display panel and a lower liquid crystal display panel, a moiré and smearing of an image can be prevented. Due to such a constitution, lowering of brightness and contrast can be suppressed.
Claims20
A display device comprising a first liquid crystal display panel, a second liquid crystal display panel arranged behind the first liquid crystal display panel, and a backlight arranged behind the second liquid crystal display panel, wherein
- between the first liquid crystal display panel and the second liquid crystal display panel, a first lens array for focusing light more strongly in a direction orthogonal to a first direction than the first direction, and a second lens array for focusing light more strongly in a direction orthogonal to a second direction different from the first direction are arranged.
A display device comprising a first liquid crystal display panel, a second liquid crystal display panel arranged behind the first liquid crystal display panel, and a backlight arranged behind the second liquid crystal display panel, wherein
- between the first liquid crystal display panel and the second liquid crystal display panel, a first lens array sheet for focusing light more strongly in a direction orthogonal to a first direction than the first direction, and a second lens array sheet for focusing light more strongly in a direction orthogonal to a second direction different from the first direction are arranged.
A display device comprising a first liquid crystal display panel, a second liquid crystal display panel arranged behind the first liquid crystal display, and a backlight arranged behind the second liquid crystal display panel, wherein
- a lens array sheet is arranged between the first liquid crystal display panel and the second liquid crystal display panel, a first lens array for focusing light more strongly in a direction orthogonal to a first direction than the first direction is formed on a first surface of the lens array sheet, and a second lens array for focusing light more strongly in a direction orthogonal to a second direction different from the first direction is formed on a second surface of the lens array sheet.
A display device comprising a first liquid crystal display panel, a second liquid crystal display panel arranged behind the first liquid crystal display panel, and a backlight arranged behind the second liquid crystal display panel, wherein
- a lens array sheet is arranged between the first liquid crystal display panel and the second liquid crystal display panel, and a micro lens array having periodicity in a first direction and a second direction different from the first direction is formed on a surface of the lens array sheet.
