Peripheries of a contact 26 for connecting a polycrystalline silicon layer 20 to a pixel electrode 28 are cut by a laser to form a cut area 50. By this cut area 50, the polycrystalline silicon layer 20 around the contact 26 is also cut. In consequence, a TFT 24 is separated from the pixel electrode 28...http://www.google.com.au/patents/US6778233?utm_source=gb-gplus-sharePatent US6778233 - Method for darkening pixel
