发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 PURPOSE:To reduce the color variance and the contrast variance between an effective display part in a display surface and an outside peripheral part by providing dummy electrodes on areas other than segment electrodes (signal electrodes) and common electrodes (scanning electrodes). CONSTITUTION:A liquid crystal is enclosed between two transparent substrates 23 and 24 to constitute a liquid crystal display device. Common electrodes 21a-21c are provided on the transparent electrode 23, and segment electrodes 22a-22d are provided on the transparent substrate 24, and they are allowed to face each other. An effective display surface 26 is provided in a liquid crystal display surface 25. Dummy electrodes 27 and 28 are provided on areas other than common electrodes 21a-21c and segment electrodes 22a-22d on transparent substrates 23 and 24. Since dummy electrodes are provided on areas other then segment electrodes and common electrodes, the color variance and the contrast variance between the effective display part in the display surface and the outside peripheral part are reduced.
