摘要： A transreflective or “semi-transmissive” liquid crystal display (LCD) device of the vertical alignment (VA) type is disclosed. The VA-LCD device includes a pair of spaced-apart substrates with a layer of liquid crystal (LC) material sandwiched therebetween. The LCD device also includes a polarization plate provided on one of the substrates, another polarization plate on the other substrate, and a matrix of rows and columns of pixels formed between the substrates. Each pixel has a reflection part and a transmission part. The LC layer is variable in thickness so that its portion at the transmission part is thicker than a portion at the reflection part. At the reflection part, an internal retardation plate having an optical phase difference is disposed between the LC layer and its associated substrate. This plate forms an angle of about 45 degrees with the absorption axis of each polarization plate.

摘要： An image is displayed by modulating TM-polarized light between the polarizer 2 and the wire grid polarizer 18 through the variation of the optical characteristic of the liquid crystal layer 12 interposed between the transparent plate 4 and the transparent plate 26. Degradation of contrast in the bright ambience is avoided by providing an absorption layer for absorbing TE-polarized light on that surface of the wire grid polarizer 18 which faces the liquid crystal layer 12.

摘要： A liquid crystal display element comprising two transparent substrates, at least one of which is transparent, and a liquid crystal layer interposed between the two substrates. A plurality of pixels and active elements for driving the liquid crystal at the plurality of pixels are incorporated into at least one of the two substrates, and an optical axis of an incident light beam upon the liquid crystal layer is present in a plane which is substantially perpendicular to a direction of orientation of liquid crystal molecules on at least one of the two substrates, and the incident light impinges upon the liquid crystal layer in a direction which is inclined by a predetermined angle to the direction of the normal line of the substrate. With this arrangement, a desired phase modulation is obtained through slight motion of the liquid crystal molecules, thereby greatly reducing the liquid crystal drive voltage.
