<p>PURPOSE:To obtain a liquid crystal image display device on which an image is displayed without irregularity uniformly throughout the image display area, by providing electrodes on the outside of the image display area of a TFT substrate and electrically floating them to use them as interference electrodes. CONSTITUTION:A TFT substrate 1 consisting of timing lines, data lines, TFT elements 4 formed at intersections between timing lines and data lines, and picture element electrodes 5 and a counter substrate 6 are kept parallel by a seal material 7, and liquid crystal 8 is enclosed between the TFT substrate 6 and the counter substrate 6 to constitute a liquid crystal image display device. In this device, electrodes are provided on the outside of the image display area of the TFT substrate 1 and are electrically floated and are used as interference electrodes 9. Consequently, the irregularity of display in the peripheral part of the image display area, the irregularity in the lapse of time due to the driving time, and increase of them which are important problems of display performance of the liquid crystal image display device are controlled. Thus, the reliability of the liquid crystal image display device is considerably improved.</p> |
