Abstract
Active matrix TFT elements array in which the number of production steps is not increased and the high production yield can be achieved. A semiconductor film is formed by patterning in an elongated island shape between pixel electrodes disposed neighboring to each other in the direction of drain lines to provide a protrusion to prevent shorting across the pixel electrodes even if photoresist film residuals are produced.
