Embodiment Construction

[0035] Hereinafter, a display device according to an exemplary embodiment of the present inventive concept will be explained in detail with reference to the accompanying drawings.

[0036] figure 1 is a circuit diagram showing pixels included in the display device according to the embodiment.

[0037] refer to figure 1 , the display device according to an exemplary embodiment of the inventive concept may include a plurality of pixels PX. Each pixel PX may emit light, and the display device may display an image formed by the light emitted from the pixel PX. Each pixel PX may include a light emitting element EL and a pixel circuit PC.

[0038] An anode of the light emitting element EL may be connected to the pixel circuit PC, and a cathode of the light emitting element EL may receive the second voltage ELVSS. The light emitting element EL can generate a current I having the same current I supplied from the pixel circuit PC EL The size corresponds to the predetermined bright...

Abstract

Exemplary embodiments of the present inventive concepts provide a display device which includes a pixel circuit, a first line disposed on the pixel circuit and a second line disposed on a same layer as the first line. A light emitting element is disposed on the first line and the second line. A connection pattern is disposed on a same layer as the first line and the second line and is disposed between the first line and the second line. The connection pattern connects the pixel circuit and the light emitting element. The connection pattern has a polygonal shape including at least six sides. A first vertex of the connection pattern is positioned at a shortest distance from the first line to the connection pattern and portions of the connection pattern between the first vertex and adjacent vertices are positioned farther from the first line than the first vertex.

Description

technical field [0001] The inventive concept relates to a display device. Background technique [0002] A display device may include a plurality of pixels for displaying images. A display device may include lines that provide signals, power, etc. for driving pixels. [0003] Recent development of display devices has resulted in an increase in the number of pixels per unit area due to increases in the size and resolution of the display devices. Therefore, due to an increase in the number of pixels per unit area, a gap between lines supplying signals, power, etc. to the pixels is reduced. The reduction of the gap between lines and pixels may cause defects such as short circuits between lines to occur. Contents of the invention [0004] Exemplary embodiments of the inventive concepts provide a display device preventing short circuit defects. [0005] According to an exemplary embodiment of the present inventive concept, a display device includes: a pixel circuit; a first ...
