Abstract: A thin-film transistor including an active layer disposed on a substrate and including a channel region, a source region connected to a side of the channel region, and a drain region connected to the other side of the channel region; a gate insulating layer on the channel region of the active layer; and a gate electrode on the gate insulating layer. A slope of each side surface of the gate electrode with respect to a boundary surface between the gate insulating layer and the gate electrode is an obtuse angle (a substantially obtuse angel). A slope of each side surface of the gate insulating layer with respect to the boundary surface between the gate insulating layer and the gate electrode is an obtuse angle (a substantially obtuse angel).

Abstract: The present disclosure relates to a display device, more particularly, to a display device in which the number of contact holes may be reduced to improve space utilization of pixels, and the method for fabricating the same. According to an embodiment of the disclosure, the display device includes a first active layer, a first transistor connected to the first active layer, a pixel electrode connected to the first transistor, a second active layer including a material different from a material of the first active layer, and a second transistor connected to the second active layer. At least a portion of the second active layer is directly connected to at least a portion of the first active layer.

Abstract: A display device includes: pixels connected to scan lines, data lines, a first power line, a second power line, and a third power line, where each of the pixels includes a light emitting device and a driving transistor for controlling an amount of current supplied to the light emitting device; and a timing controller for generating output data by using input data. The pixels emit light in response to a data signal corresponding to the output data during a normal driving period, and receive a bias voltage during a recovery driving period in which the pixels do not emit light after the normal driving period. The timing controller is configured to control a length of the recovery driving period in response to the input data.
