Abstract: A display device includes a first substrate, an insulating layer, a plurality of display elements, a plurality of first spacers, and a second substrate. The first substrate includes a transmission area, a display area surrounding at least a portion of the transmission area, and a first non-display area located between the transmission area and the display area. The insulating layer is arranged on the first substrate in the display area and the first non-display area. The plurality of display elements are disposed on the insulating layer in the display area. The plurality of first spacers each has an island shape and are spaced apart from each other on the insulating layer in the first non-display area. The second substrate faces the first substrate.

Abstract: A display apparatus includes a buffer layer on a substrate, a first hole penetrating the buffer layer and exposing a portion of the substrate, a display layer with display elements and bypass lines on the buffer layer, a second hole penetrating the display layer and connected to the first hole, and an encapsulation member covering the display elements and the bypass lines. The bypass lines are configured to extend along a portion of a perimeter of the second hole and are disposed between the second hole and the display elements. At least a portion of an upper surface of the buffer layer is exposed by the second hole.

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.
