Patent ID: 7233155

Claim:
A method for making an electrooptic device that includes a substrate to support an electrooptic material and an electrical-element forming region including many thin-film switching elements formed on the substrate, the method comprising: forming an inspection pattern to inspect electrical characteristics of the thin-film switching elements inside the electrical-element forming region simultaneously with forming of the thin-film switching elements inside the electrical-element-forming region of the substrate, and forming inspection pads electrically connected to the inspection pattern inside the electrical-element-forming region; examining the electrical characteristics of the inspection pattern by placing inspection terminals into contact with the inspection pads; manufacturing the electrooptic device using a substrate that has been determined to have satisfactory quality as a result of inspection; the electrical-element forming region including a pixel region in which pixels are arranged in a matrix, the pixels including pixel electrodes to drive the electrooptic material and the thin-film switching elements formed as pixel-switching active elements to drive the pixel electrodes, further including forming the inspection pattern and the inspection pads at a peripheral region inside the pixel region; and in assembling the electrooptic device using the substrate, the center region of the pixel region being an effective pixel region in which effective pixels to display images are arranged in a matrix, and the peripheral region inside the pixel region being a dummy pixel region covered with a light-shielding member, the dummy pixel region including dummy pixels that do not directly contribute to the display of images.
