Abstract: A driver is disposed in a display panel, and includes a plurality of stages. At least one stage of the plurality of stages includes an input circuit which transfers an input signal to a first node in response to at least one of a clock signal and an inverted clock signal, and inverters which generate an output signal based on a voltage of the first node. At least one of the inverters includes a p-type metal-oxide-semiconductor (“PMOS”) transistor and an n-type metal-oxide-semiconductor (“NMOS”) transistor connected in series between a line transferring a relatively high gate voltage and a line transferring a relatively low gate voltage. A first active region of the PMOS transistor includes a material different from a material of a second active region of the NMOS transistor.

Abstract: A display device including a substrate, a plurality of first data lines and a plurality of second data lines. The substrate includes a display area, in which a hole is formed, and a hole edge area surrounding the hole. The plurality of first data lines are disposed on the substrate, extend in a first direction in the display area, are arranged in a second direction orthogonal to the first direction, and bypass the hole along the hole edge area. The plurality of second data lines are disposed on the substrate, extend in the first direction in the display area, are arranged adjacent to the plurality of first data lines, and bypass the hole along hole edge area. In the hole edge area, each of the plurality of first data lines and the plurality of second data lines are disposed on three layers different from each other.

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.
