Abstract

A display device includes subpixels disposed in a display area for displaying an image. Each subpixel includes a light emitting element; a driving transistor for driving the light emitting element; and a transistor whose turn-on or turn-off may be controlled by a gate signal supplied through a gate line. The subpixels includes a subpixel disposed in a specific area in the display area, and such subpixel may include a compensation capacitor formed by overlapping of a gate node of the driving transistor or a connection pattern connected to the gate node of the driving transistor and the gate line. A voltage level of the gate signal supplied through the gate line is changed to a lower voltage level at a timing at which a data voltage or a voltage resulting from changing of the data voltage is applied to the gate node of the driving transistor.
