A simplified tri-layer process for forming a thin film transistor matrix for a liquid crystal display is disclosed. By forming a pixel electrode layer before a gate metal layer, a remaining portion of the gate metal layer surrounding the pixel electrode can function as a black matrix after properly patterning...http://www.google.fr/patents/US6448117?utm_source=gb-gplus-shareBrevet US6448117 - Tri-layer process for forming TFT matrix of LCD with gate metal layer around pixel electrode as black matrix
