摘要： An image display apparatus configured by a display panel having an image memory element in a pixel, which achieves low power consumption. A nonvolatile image memory element 1, which can change the resistance value by phase change, is connected to a pixel electrode 25 of a liquid crystal element 5. The output of a thin-film transistor 17 driven by scanning and signal electrode lines 7, 9 is connected to the pixel electrode 25. When the scanning electrode line 7 is selected to have a high level voltage, the thin-film transistor 17 is turned on and a current signal flowing through the signal electrode 9 is sent through the image memory element 1 to a reference electrode line 15. Depending on the current value or pulse width passing through the image memory element 1, the resistance of the image memory element 1 is changed and is stored as a resistance value. A liquid crystal drive voltage to be applied to the liquid crystal element 5 is varied depending on the resistance of the image memory element 1 and an image is displayed on the liquid crystal element 5.

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.
