Liquid crystal device and projection-type display apparatus

摘要

In an element substrate of a liquid crystal device, in a peripheral region interposed between an image display region and a seal material, a peripheral electrode to which a potential is applied for trapping ionic impurities which is different from a common potential applied to a dummy pixel electrode or the like is formed. In the peripheral electrode, an electrode width of a first portion opposing a sealing material provided at a liquid crystal injection opening of the seal material is set to be greater than electrode widths of the other portions.

1. A liquid crystal device comprising:
an element substrate provided with, on one surface side, an image display region in which a plurality of pixel electrodes are arranged; a counter substrate provided with a common electrode to which a common potential is applied; a seal material which bonds the element substrate and the counter substrate to each other, the seal material having a liquid crystal injection opening which is disposed between a first side of the element substrate and the image display region; a sealing material which seals the liquid crystal injection opening through which liquid crystals are injected into a region surrounded by the seal material; a liquid crystal layer which is held in the region surrounded by the seal material between the element substrate and the counter substrate; and a peripheral electrode which is provided in the element substrate so as to extend along the seal material in a peripheral region interposed between the image display region and the seal material, and to which a potential is applied that is different from the common potential, wherein
the peripheral electrode includes a first portion and a second portion,the first portion is disposed between the sealing material and the image display region, the first portion extending along the first side of the element substrate so as to have an electrode width Wb in a direction intersecting with the first side of the element substrate,the second portion is disposed between the seal material and the image display region, the second portion extending along a second side of the element substrate so as to have an electrode width Wa in a direction intersecting with the second side of the element substrate,the second side of the element substrate is a side other than the first side of the element substrate, andthe electrode width Wb is greater than the electrode width Wa.
