摘要： The present disclosure relates to a pixel displaying an image. A pixel includes an organic light emitting diode, a first transistor controlling an amount of current flowing from a first driving power supply to a second driving power supply via the organic light emitting diode in response to a voltage of a first node; a storage capacitor connected between the first node and the first driving power supply; a second transistor connected between a data line and the first node and turned on when a scan signal is supplied to a first scan line, and an auxiliary transistor connected between the second transistor and the data line and turned on when a scan signal is supplied to a second scan line. The second transistor and the auxiliary transistor have an overlapping turn-on period, and the second transistor is turned off before the auxiliary transistor is turned off.

摘要： A curved liquid crystal display (LCD) device includes: a first curved substrate; a second curved substrate; a first curved liquid crystal alignment layer disposed between the first curved substrate and the second curved substrate; a second curved liquid crystal alignment layer includes polymerized reactive mesogens, and a polymerization initiator; and a liquid crystal layer including first and second liquid crystal molecules disposed between the first curved liquid crystal alignment layer and the second curved liquid crystal alignment layer. In an initial state when no electric field is applied, the first liquid crystal molecules are relatively vertically aligned as compared with the second liquid crystal molecules with respect to the first curved substrate and the second liquid crystal molecules are relatively tilt-aligned as compared with the first liquid crystal molecules with respect to the first curved substrate, wherein the first curved liquid crystal alignment layer does not have a polymerization initiator.
