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: There is provided an organic light emitting display device. The organic light emitting display device includes a two pixel columns arranged on the substrate to be adjacent to each other, a first data line and a second data line that are provided between the two pixel columns, at least one scan line that intersects the first and second data lines, and first and second insulating layers sequentially laminated on the substrate. Pixels included in the two pixel columns are connected to one of the first data line and the second data line and the scan line. The first data line is formed between the first insulating layer and the second insulating layer. Therefore, coupling generated between adjacent data lines is reduced so that picture quality of the organic light emitting display device is improved.

Abstract: A display device includes a data driver and a demultiplexer. The data driver supplies an image data signal to the demultiplexer. The demultiplexer timely divides the image data signal and outputs the divided image data signal to a data line. The demultiplexer supplies the image data signal to a first pixel column, and supplies the image data signal to a second pixel column after a predetermined time elapses, during a first frame period. The demultiplexer supplies the image data signal to the second pixel column, and supplies the image data signal to the first pixel column after a predetermined time elapses, during a second frame period.
