Abstract: A pixel includes: a first transistor including a gate electrode connected to a first node, a first electrode connected to a first power line for receiving a first driving power voltage via a second node, and a second electrode connected to a third node; a light-emitting element including a first electrode connected to the third node, and a second electrode connected to a second power line; a second transistor connected between a data line and the second node, and including a gate electrode connected to a first scan line; and a third transistor connected between the first node and a third power line for receiving an initialization power voltage. The second transistor is set to a turn-on state during at least a portion of a turn-on period of the third transistor. The initialization power voltage is set to be lower than a data signal.

Abstract: A liquid crystal display includes a substrate on which a pixel region is defined, a first sub-pixel electrode in the pixel region on the substrate, an insulating layer on the first sub-pixel electrode, a second sub-pixel electrode in the pixel region on the insulating layer, a floating electrode in the pixel region on the insulating layer and disconnected from the second sub-pixel electrode, a liquid crystal layer on the second sub-pixel electrode and the floating electrode, and a common electrode disposed on the liquid crystal layer. The floating electrode includes first to fourth floating electrodes in first to fourth quadrants of the pixel region, respectively. The first to fourth floating electrodes are separated from one another, and the first sub-pixel electrode partially overlaps the second sub-pixel electrode and the first to fourth floating electrodes.
