摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates each provided with an alignment control layer, and a liquid crystal layer comprising a liquid crystal material and disposed between the substrates with a spacer member. In the device, the spacer member has an electrical conductivity larger than that of the liquid crystal material. Further, the liquid crystal layer containing the spacer member has a first resistance in a direction of a normal to the substrates in a prescribed temperature range substantially lower than a second resistance of a corresponding liquid crystal layer, in the identical direction, consisting only of the liquid crystal material and having the identical plane area and thickness. The liquid crystal device is effective in providing an improved drive margin in a wide temperature range while suppressing a DC offset voltage component applied to the liquid crystal layer.

摘要： A display device is constituted by a pair of oppositely disposed substrates spaced from each other and having thereon scanning electrodes and data electrodes intersecting the scanning electrodes, respectively, and a layer of optical modulation substance, e.g., a liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and data electrodes and so that a white display region and a black display region can be formed at a varying areal ratio therebetween in each pixel. In the device, a site forming a nucleus of a black display region in one pixel and a site forming a nucleus of a white display region in another pixel adjacent to said one pixel are disposed to be adjacent to each other. As a result, a halftone display can be effected according to the areal method using a cell having a simple thickness gradient while avoiding appearance of ugly continuous lines diminishing a halftone display effect. The device is also suitable for a temperature compensation according to the pixel shift method.

摘要： A display panel includes a matrix of pixels each constituted by a pair of oppositely disposed electrodes and a liquid crystal disposed between the electrodes. A current signal, particularly one associated with inversion of spontaneous polarization of the liquid crystal is detected at plural pixels. The display panel is driven by applying drive signals thereto while correcting the drive signals based on the detected current signal. As a result, a threshold distribution typically attributable to a temperature distribution on the display panel is accurately compensated for. The display system thus constituted is particularly useful for gradational display.
