Moir&#xe9;s due to interference between two liquid crystal display panels in a display device which achieves three-dimensional displaying by using two liquid crystal display panels is to be prevented. By disposing a lenticular lens array between an upper liquid crystal display panel and a lower liquid crystal display panel, moir&#xe9;s and image blurs are prevented. This configuration can prevent the luminance levels and contrast of images from dropping.

Liquid crystal display device having a lens array being arranged the extending direction of the longitudinal axis of the lens

A display device includes a display panel having a front surface and a back surface, a first and second frame, a first elastic member arranged between the first frame and the front surface of the display panel, and a second elastic member arranged between the second frame and the back surface of the display panel, the second elastic member extending in parallel to the first elastic member. A hardness of the first elastic member varies along an elongated direction of the first elastic member so as to have a high-hardness portion, and wherein a hardness of a first portion of the second elastic member which corresponds in location to the high-hardness portion of the first elastic member has a low hardness, a hardness of a second portion of the second elastic member which corresponds in location to the low-harness portion of the first elastic member has a high hardness.

Display device with elastic members having portions of different hardness or different widths

A display device includes a display panel, a frame, an elastic spacer arranged on a peripheral portion of the display panel in parallel to the edge of the display panel, the elastic spacer being arranged between the display panel and the frame. A hardness of the elastic spacer varies along the length-side direction of the elastic spacer.

The present invention prevents a moir&#xe9; 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 moir&#xe9; and smearing of an image can be prevented. Due to such a constitution, lowering of brightness and contrast can be suppressed.

Display device

A display device includes a fixed first display element and a movable second display element, the first display element and the second display element assume a first state in which the first display element and the second display element are arranged individually and a second state in which the first display element and the second display element are arranged individually in an overlapped manner.

Display device convertible from two dimensional display to three dimensional display

A display device has a display panel, a frame, and an elastic spacer arranged on the periphery of the display panel in parallel to the edge of the display panel. The elastic spacer is arranged between the display panel and the frame, and the hardness of the elastic spacer is varied along the length-side direction of the elastic spacer.

Display device with elastic spacers having varying widths and hardness

The invention provides a high quality liquid crystal panel with low non-uniformity by enveloping a pair of glass substrates sandwiching an uncured thermosetting seal member with heat-resistant metal sheets, bringing the insides of the sheets into a substantially hermetically closed state to decompress the space around the substrates, pressing the glass substrates and the seal member by a pressure difference from the atmospheric pressure in a predetermined space created by the enveloping sheets, heating the sheets, the glass substrates and the seal member with a heater disposed at a position remote from the sheet and curing the seal member, and maintaining the gap between the pair of glass substrates to prevent non-uniformity of the gap between the pair of glass substrates constituting the liquid crystal panel.
