Abstract
Embodiments of the disclosure concern display devices. The voltage line for supplying driving voltage to the cathode electrode of the light emitting element in the subpixel and the voltage line for supplying voltage for initializing the subpixel are integrated together. This allows for use of fewer voltage lines in the active area, along with easier arrangement of the voltage lines. The wire resistance may be reduced by adjusting the width of the voltage lines. The reduction in wire resistance may decrease brightness deviation or increase the aperture ratio or transmittance of the subpixel, thus allowing the display device higher light emission efficiency or transmittance.
