Abstract: Provided are a display device and a method of manufacturing the same. A display device comprises a display area, a non-display area, signal lines, and compensating capacitors. The display area and the non-display area are defined on a substrate. The signal lines are located within the display area, and their wiring lengths differ depending on location. The compensating capacitors are connected to at least one of the signal lines.

Abstract: An organic light emitting display in which each pixel has a driving thin film transistor for adjusting the current flowing through an organic light emitting diode based on a voltage applied to a gate electrode, includes the gate electrode of the driving thin film transistor; a signal line adjacent to the gate electrode of the driving thin film transistor; and a first shielding electrode located above the gate electrode of the driving thin film transistor, with a first insulating layer therebetween, wherein the first shielding electrode extends further towards the signal line than the gate electrode of the driving thin film transistor.

Abstract: A display device includes a pixel array, a switch element, and inspection lines. In a display area, at least a portion of an outer region includes a curved section and pixels to which a data line is connected are disposed. The switch element is disposed in a bezel area outside the display area, and supplies a test voltage to the data line in response to an enable signal. The inspection lines connect an inspection pad part and switch elements and are disposed in a staircase form along the curved section. The switch elements are disposed along the inspection lines and include first and second switch elements disposed to be adjacent to each other in a direction perpendicular to each other.

Abstract: A circuit has a first portion configured to act as a shift register to provide an output signal via an output terminal, and a second portion configured to act as an inverter to invert the output signal at the output terminal of said first portion from a logic high state to a logic low state or vice versa. This is to forcibly turn off one or more transistors in a pixel circuit that provides subpixel or pixel-related control in an OLED display, such that an anode voltage of an organic light emitting diode does not exceed a turn-on voltage thereof.
