摘要： 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.

摘要： 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.
