Patent ID: 8582041

Claim:
A display device which comprises a first liquid crystal display panel that displays images, a second liquid crystal display panel that displays images related to the images displayed on the first liquid crystal display panel disposed behind the first liquid crystal display panel with prescribed spacing in-between, each one of the first liquid crystal display panel and the second liquid crystal display panel including a scanning line and a video signal line, wherein images of the first liquid crystal display panel and images of the second liquid crystal display panel have the same polarization, and a backlight disposed behind the second liquid crystal display panel to enable the viewer to recognize an image from in front of the first liquid crystal display panel, wherein a lens array arranged in a specific direction with respect to directions of the scanning lines of the first and second liquid crystal display panels is disposed between the first liquid crystal display panel and the second liquid crystal display panel wherein the specific direction being the extending direction of the longitudinal axis of the lens, wherein the lens array is configured to more powerfully focus light in a direction at a substantially right angle to the specific direction, wherein a first polarizing board is provided on an outer surface of the first liquid crystal display panel facing away from the second liquid crystal display, a second polarizing board is provided on an outer surface of the second liquid crystal display panel facing away from the first liquid crystal display, and no polarizing board is disposed between inner surfaces of the first liquid crystal display panel and the second liquid crystal display panel which inner surfaces face each other, wherein, when viewing the lens array two-dimensionally from in front of the outer surface of the first liquid crystal display panel, the specific direction of the lens array has a diagonal angle greater than 0 degree to a direction to which a scanning line extends, and is substantially identical with the polarizing axis of the first polarizing board or of the second polarizing board, wherein the specific direction in which the lens array is arranged is chosen to reduce moiré visible to a viewer.
