A display device that includes multiple pixels, each pixel includes a light emitting element, a multiple of transistors, multiple voltage sources and capacitors. The pixel circuit is designed and the pixels are driven so that a driving current going through the light emitting element is independent of a threshold voltage of a driving transistor of the multiple transistors. As a result, luminance variation due to threshold voltage can be minimized, and residual image can be reduced.

Pixel and display device including the same

A display device includes: a first display panel; a second display panel opposite to the first display panel; and an electro-optical active layer between the first display panel and the second display panel, wherein the first display panel includes a thin film transistor including a gate electrode, a source electrode, a drain electrode and a semiconductor layer, a gate line configured to transmit a gate signal to the gate electrode of the transistor and extending in a first direction, and a sensing electrode extending in the first direction and overlapping the gate line, where the sensing electrode and the gate electrode define a capacitor.

Display device including sensor

A display device includes a first substrate including a first surface, on which a touch by an external object occurs, and a second surface opposite to the first surface, a plurality of driving signal lines positioned on the second surface of the first substrate, where the plurality of driving signal lines transmits a driving signal for displaying an image, a plurality of pixels including a plurality of switching elements connected to the plurality of driving signal lines, a sensing signal line positioned on one of the first surface and the second surface of the first substrate, where the sensing signal line transmits a sensing signal generated based on the touch by the external object, and a touch sensor unit including a sensing capacitor defined by at least one driving signal line of the plurality of driving signal lines and the sensing signal line.
