Abstract: A display device has a substrate with a first pixel area and a second pixel area smaller than the first pixel area. First pixels in the first pixel area are connected with first scan lines. Second pixels in the second pixel area are connected with second scan lines. A first scan driver supplies a first scan signal to the first scan lines, and a second scan driver supplies a second scan signal to the second scan lines. A first signal line supplies a first driving signal to the first and second scan drivers. The first signal line includes first sub signal line to supply the first driving signal to the first scan driver, a second sub signal line to supply the first driving signal to the second scan driver, and a first load matching resistor connected between the first sub signal line and the second sub signal line.

Abstract: A display device includes a substrate, a pixel area, and a plurality of data lines. The substrate includes display and non-display areas. The pixel area is in the display area and includes a first pixel column and a second pixel column. The pixels in the first and second columns emit light of different colors. The data lines are respectively coupled to the first pixel column and the second pixel column. In the non-display area, a data line is coupled to one of the first or second pixel columns corresponding to a color on which influence of a resistance is greater than on another color. The data lines has a line or contact structure with a resistance less than a resistance of a line or contact structure of a remaining data line coupled to a remaining pixel column.

Abstract: A display device includes a substrate which includes a display area and a non-display area, a pixel unit which is provided in the display area and includes a plurality of pixel columns, and data lines which are respectively connected to the pixel columns and apply data signals to the pixel columns. The non-display area includes a fanout area, a bent area, and a pad area which are sequentially arranged. The respective data lines are disposed on different layers in the fanout area and the pad area. A resulting display device can reduce resistance deviation between data signals in a first data line and a second data line, thereby reducing vertical line defects.
