Abstract

The present invention relates to a display device. A display device according to an embodiment of the present invention comprises: a plurality of data lines for supplying a data signal; a plurality ofpixels each including a light emitting element, a first transistor for controlling an amount of current flowing through the light emitting element, and a second transistor connected between the firsttransistor and any one of the plurality of data lines; and a bridge pattern connected to the second transistor through a first contact hole, wherein the data lines are provided on a layer other thanthe bridge pattern, and connected to the bridge pattern through a second contact hole, and the first contact hole and the second contact hole may overlap with each other as viewed from a plane.

Description

technical field [0001] Various embodiments of the present disclosure relate to a display device. Background technique [0002] An organic light emitting display device includes a plurality of pixels including a display element as a light emitting element. Each pixel is connected to a line, and includes a plurality of thin film transistors to drive light emitting elements. [0003] Unintended parasitic capacitors are formed between the line components and the thin film transistors. The parasitic capacitors degrade the display quality of the organic light emitting display device. Contents of the invention [0004] technical problem [0005] Various embodiments of the present disclosure relate to a display device capable of effectively removing a parasitic capacitor that may be formed between a line and a transistor in a pixel, thereby improving display quality. [0006] Technical solutions [0007] According to aspects of the present disclosure, a display device may inc...
