Abstract: A display device includes a first pixel row, a first first-structure transmission line, a first second-structure transmission line, a first transistor, and a second transistor. The first pixel row includes a first first-color sub-pixel and a second first-color sub-pixel both for displaying a first color. The first second-structure transmission line neighbors the first first-structure transmission line with no intervening transmission line analogous to the first first-structure transmission line or the first second-structure transmission line being disposed between the first first-structure transmission line and the first second-structure transmission line. The first transistor is electrically connected through the first first-structure transmission line to the first first-color sub-pixel and receives a first test voltage. The second transistor is electrically connected through the first second-structure transmission line to the second first-color sub-pixel and receives a second test voltage different from the first test voltage.

Abstract: A display apparatus includes a display area including pixels; a non-display area adjacent to the display area; a first planarization layer located in the display area and the non-display area; a second planarization layer on the first planarization layer; an organic insulating layer on the second planarization layer; a first dam on the first planarization layer, including the second planarization layer and the organic insulating layer, and surrounding the display area; a second dam disposed outside the first dam, including the second planarization layer and the organic insulating layer, and surrounding the first dam; and a monitoring bank disposed between the display area and the first dam and including the second planarization layer and the organic insulating layer. A thickness of the second planarization layer included in the monitoring bank is less than a thickness of the second planarization layer included in the first dam.
