A display apparatus includes a light-emitting diode, a driving transistor configured to control a driving current supplied to the light-emitting diode, a compensation transistor connected between a second terminal of the driving transistor and a gate electrode of the driving transistor and configured to compensate for a threshold voltage of the driving transistor, a first connection electrode configured to connect the gate electrode of the driving transistor and a first terminal of the compensation transistor to each other, and a driving voltage line on an insulating layer covering the first connection electrode, covering the gate electrode of the driving transistor, and having an opening overlapping the first connection electrode.

Display apparatus

A display panel includes: sub-pixels each including a storage capacitor configured to have a data voltage written thereto; a capacitor node line connected to the storage capacitor of at least one of the sub-pixels; a compensation reference voltage line configured to receive a compensation reference voltage; a first power supply voltage line configured to receive a first power supply voltage; a first connection transistor configured to connect the compensation reference voltage line to the capacitor node line based on an emission signal; and a second connection transistor configured to connect the first power supply voltage line to the capacitor node line based on the emission signal.

Display panel and display device including the same

A display device includes a display panel including a first pixel, a second pixel, and a connection line connecting the first pixel and the second pixel. Each of the first pixel and the second pixel includes a light emitting element, a first transistor including a first electrode, a second electrode electrically connected to the light emitting element, and a gate electrode, a second transistor connected between a first driving voltage line and a connection node and including a gate electrode connected to an emission line, a third transistor connected between a second driving voltage line and the connection node and including a gate electrode connected to the emission line, and a capacitor connected between the gate electrode of the first transistor and the connection node. The connection node of the first pixel is electrically connected to the connection node of the second pixel through the connection line.
