Abstrakt: Input-integrated displays with a tablet and liquid-crystal display (LCD) have been developed for computers. In the input-integrated displays, parallax due to the thickness of a glass causes the difference between the positions of a pen and the displayed image. To eliminate the parallax problem, a fiber plate was used for the upper substrate of an LCD Steal of a conventional glass plate and the newly developed LCD was evaluated. (1) It was found that when a fiber was used for the upper substrate of the LCD and liquid-crystal material with a polarization charateristic (for example, one with dichromatic coloring matter which has anisotropic characteristics in the absorption of visible light in the long and short axes directions of liquid-crystal molecules), the parallax observed when a glass plate was used almost disappeared. (2) The relationship among the pen position, glass plate thickness, and dot-pitch of an LCD for conventional LCDs was obtained. Using the relationship, it was clarified that the disturbance due to the parallax could be eliminated. [ABSTRACT FROM AUTHOR]
