Abstract: A display device includes at least one transistor. The transistor has an active pattern including a first active area and a second active area. The first active area includes a first channel area and an n-doped area contacting the first channel area. The second active area includes a second channel area and a p-doped area contacting the second channel area. A first insulation layer covers at least a portion of the active pattern. A first gate electrode is disposed on the first insulation layer and at least partially overlaps the first channel area. A second gate electrode is disposed on the first insulation layer and at least partially overlaps the second channel area. A taper angle of the second gate electrode is larger than a taper angle of the first gate electrode.

Abstract: A display apparatus includes a display panel, a timing controller, a data driver, and a gate driver. The timing controller receives image data at a number of frames per second of a first level and generates a gate control signal and a data control signal. The timing controller includes an image converter that operates in film mode or normal mode when the input image data are moving image data, and that outputs film image data at a number of frames per second of second level lower than the first level during the film mode. The data driver applies a data voltage corresponding to the film image data to the display panel based on the data control signal. The gate driver applies a gate voltage to the display panel based on the gate control signal. The display panel operates at a frequency of the second level during the film mode.
