IPC: G02F1/1333
Filed: 1994-08-08
Abstract: PURPOSE:To shorten an adequate visual range in the case of using a display panel as an active barrier display panel and to hardly cause color slurring by parallax in the case of externally attaching a color filter by constituting the display panel by arranging a pair of base materials to face each other and making the thickness of either base material different from that of the other base material. CONSTITUTION:The active barrier display panel 20 is constituted by arranging glass base plates 22 and 26 to fact each other. The thickness of the glass base plate 22 is made different from that of the glass base plate 26, and a picture displaying liquid crystal panel 10 functioning as an optical element is arranged on the thin glass base plate 22 side. Therefore, a distance between barrier generated in a liquid crystal layer 24 and a displayed picture displayed on the liquid crystal layer 14 is shortened. Since the distance between the active barrier and the displayed picture is shortened, the adequate visual range where a three-dimensional image is observed is shortend, thereby facilitating stereoscopic vision.
