ABSTRACT:
In an electrode substrate used in a liquid crystal display device, a contact hole for connecting a signal line to a drain electrode of a pixel thin film transistor is provided in a position overlapping a pixel electrode in order to improve yields by reducing a short circuit between adjacent pixel electrodes. With this configuration, the contact hole does not exist at a boundary between the two adjacent pixel electrodes. Accordingly, the pixel electrodes do not suffer an influence of an electrode material remaining at a recess of the contact hole, and a short circuit between the adjacent pixel electrodes can be thereby prevented.
