Abstract

A display device includes a substrate, first and second data lines, and first and second sub-pixel units. The first sub-pixel unit includes a first electrode and a first light emitting layer disposed on the first electrode. The first electrode has a first region with a first area overlapping the first data line. The second sub-pixel unit includes a second electrode and a second light emitting layer disposed on the second electrode. The second electrode has a second region with a second area overlapping the second data line, wherein the first area is greater than the second area. The luminescence color of the first light emitting layer and the luminescence color of are different, and the luminescence color of the first light emitting layer is blue.
