摘要： A display apparatus includes a first data line extending from a first peripheral area into a display area, a second data line extending from a second peripheral area into the display area, a pixel electrode, a second input line disposed in the first peripheral area, and a connecting line having a first end electrically connected to the second data line in the second peripheral area and a second end electrically connected to the second input line in the first peripheral area. The connecting line passes through the display area by extending over the first data line while not contacting the first data line, and at least a portion of the connecting line and the pixel electrode include a same material.

摘要： An organic light-emitting display includes a first pixel adjacent to a second pixel and a plurality of driving voltage lines to apply driving voltages to the first pixel and the second pixel. The driving voltage lines extend in a first direction crossing the first pixel and the second pixel and a second direction crossing the first direction. Each of the first and second pixels includes a first driving transistor and a second driving transistor that are symmetrical to each other with respect to a boundary between the first pixel and the second pixel, and a first compensation transistor and a second compensation transistor that are asymmetrical to each other with respect to the boundary.
