Abstract: A thin film transistor array substrate includes: a base substrate; a first transistor including a first electrode on a surface of the base substrate, a spacer, on the first electrode, a second electrode on the spacer, a first active layer contacting the first electrode, the spacer and the second electrode, and a first gate electrode opposite to the first active layer with a first insulating layer interposed therebetween; a storage capacitor including a first storage electrode integrally connected to the first electrode or the second electrode, and a second storage electrode opposite to the first storage electrode with the first insulating layer interposed therebetween, where the second storage electrode is integrally connected to the first gate electrode; and a second transistor electrically connected to the storage capacitor, where the second transistor includes a second active layer extending in a direction intersecting the base substrate.

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.
