    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 including a pixel region and a peripheral region. A plurality of pixels is disposed in the pixel region of the substrate. Each of the plurality of pixels includes a light emitting element. Data lines and scan lines are connected to each of the plurality of pixels. A power line is configured to supply power to the plurality of pixels. The power line includes a plurality of first conductive lines and a plurality of second conductive lines intersecting the plurality of first conductive lines. The plurality of second conductive lines is arranged in a region between adjacent light emitting elements of the plurality of pixels. At least some of the plurality of second conductive lines extend in a direction oblique to a direction of extension of the data lines or the scan lines.

    Abstract: A display device includes first and second initialization voltage sources and first and second pixel circuits. The first initialization voltage source provides a first initialization voltage. The second initialization voltage source provides a second initialization voltage less than the first initialization voltage. The first pixel circuit includes a first organic light emitting diode. The second pixel circuit includes a second organic light emitting diode with an organic material having a band gap different from a band gap of an organic material in the first organic light emitting diode. The first pixel circuit is coupled to the first initialization voltage source and the second initialization voltage source. The second pixel circuit is coupled to a single initialization voltage source.

    Abstract: A display device includes a substrate, data lines arranged on the substrate, the data lines to which data voltages are applied, scan lines arranged on the substrate, the scan lines to which scan signals are applied, and a pixel connected to one of the data lines and at least one of the scan lines. The pixel includes a light emitting element, a driving transistor which supplies a driving current flowing between a first electrode and a second electrode to the light emitting element in accordance with the data voltage of the data line applied to a gate electrode, a first transistor between the gate electrode and second electrode of the driving transistor, a shielding electrode overlapping at least a part of the first transistor in a thickness direction of the substrate. The shielding electrode does not overlap the data lines in the thickness direction of the substrate.
