    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.

    摘要： The driving voltages for monochromatic images are sequentially applied to each of a plurality of pixels included in the display unit so as to cause each of the pixels to sequentially display the monochromatic images. A time-sequential arrangement of the driving voltages for the 2s (s is an integer equal to or larger than 2) monochromatic images that include the three primary colors of red, blue, and green is employed as one unit. Then, the one unit of arrangement of the driving voltages is sequentially applied periodically to each of the pixels included in the display unit so as to cause each of the pixels to sequentially display the monochromatic images arranged in accordance with the arrangement, wherein a color of the monochromatic image is any one of the three primary colors of red, blue, and green, each of the pixels included in the display unit being caused to display the monochromatic image at one point in time.

    摘要： In a backlight using an LED, area control is performed such that the backlight is lit only in the bright area of the screen and the backlight is not lit in the dark area. The temperature change in the light emission efficiency of the LED is large. The temperature of the lit LED is high in area control, so that when a completely gray screen is displayed after the area control, the light emission efficiency of the LED decreases in the previously illuminated area, resulting in the occurrence of uneven brightness. The present invention prevents the uneven brightness of the screen in area control, by reducing the temperature change in the light emission efficiency of the LED to 5% or less, and more preferably 3% or less, in a temperature range of 50° C. to 90° C.

    摘要： In a liquid crystal apparatus in which a white light of a fluorescent tube corresponding to a linear light source repeats plural times of diffusions and reflections between a reflection sheet and a diffusion plate, and is thereafter input as a back light to a liquid crystal panel corresponding to a display screen, an object of the invention is to make it possible to secure a brightness uniformity even if the liquid crystal apparatus is thinned. It is possible to prevent a brightness unevenness caused by a short distance from the reflection sheet to the diffusion plate, by preventing a deformation (a deformation which is convex toward the fluorescent tube) of the diffusion plate due to a thermal expansion of the diffusion plate caused by a heat generation of the fluorescent tube, by arranging at least one pin mold hold so as to support a portion near an approximately center of the diffusion plate.
