Abstract
A UV laser beam is selectively irradiated on an active layer (semiconductor layer) of a second TFT in a pixel, so as to degrade crystallinity of the active layer and thereby execute electrical disconnection. According to this method, dimming out of pixels can be performed without generating undesirable influences in other components. By directing the laser beam to a portion of the active layer located beneath the gate electrode, the laser beam can be reflected by the gate electrode, allowing execution of a more efficient laser irradiation.
