ABSTRACT:
An object of the invention is to facilitate identifying the display color of each pixel during a test process and to apply a correction to a defective switching device in accordance with a test criterion established for each display color. On one transparent substrate, there are formed gate wiring and source wirings intersecting at right angles to each other so that insulation therebetween is maintained, and a pixel electrode and a TFT device are formed for each pixel, thus constructing one substrate member. On another transparent substrate, there is formed a counter electrode facing the pixel electrodes, and identifying means for identifying the display color of each pixel is formed on the side opposite from the side where the counter electrode is formed, the identifying means then being covered with a light-blocking member, thus constructing the another substrate member. The light-blocking member contains openings formed therethrough in portions facing the pixel electrodes. Since the display color of each pixel can be identified using the identifying means, a defective switching device in a pixel can be corrected in accordance with a correction criterion established for each display color.
