    Abstract: A display apparatus includes a display area extending in a first direction and a second direction, first to fourth sub-pixels, and a spacer. The first sub-pixel emits a first color light, and includes first and second sides extending in a third direction inclined at a predetermined angle with the first direction, and third and fourth sides extending in a fourth direction perpendicular to the third direction. The second sub-pixel emits a second color light, and is disposed adjacent to the second side of the first sub-pixel in the fourth direction. The third sub-pixel emits a third color light, and is disposed adjacent to the fourth side of the first sub-pixel in the third direction. The fourth sub-pixel emits the first color light, and is disposed adjacent to the second and third sub-pixels. The spacer is disposed between the first and second sub-pixels and between the third and fourth sub-pixels.

    IPC: G09G3/20

    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.
