Abstract: A display panel in one example includes pixel blocks having subpixels disposed in a display area, a bezel area disposed outside the display area, and mode control line sets individually connected to pixel blocks. Each mode control line set includes a first mode control line for supplying a first mode control signal and a second mode control line for supplying a second mode control signal. Each subpixel includes a driving transistor connected to a first power line, a first light emitting device connected to the driving transistor through a first mode control transistor controlled by the first mode control signal, a second light emitting device connected to the driving transistor through a second mode control transistor controlled by the second mode control signal, a first lens region disposed on the first light emitting device, and a second lens region disposed on the second light emitting device.

Abstract: Disclosed is a display device with a built-in touch screen. The display device includes a gate electrode and a pixel electrode on a substrate, an activation layer and a sensing contact portion, a source electrode and a drain electrode, and a gate insulation layer provided between the gate electrode and the activation layer and between the pixel electrode and the sensing contact portion. Thereby, it is possible to reduce the number of data lines arranged in the display panel. Also disclosed is a method of fabricating a display device with a built-in touch screen. The method includes forming a first gate electrode and a pixel electrode according to a first mask process, and forming an activation layer, a source electrode, a drain electrode, and a touch sensing line according to a second mask process. Thereby, it is possible to reduce the number of mask processes.
