AI Technical Summary

Benefits of technology

The patent describes a display device that uses three patterns to transfer driving voltage. This design eliminates the need for additional contact holes, which allows for a freer shape of one of the patterns. The technical effect is that fewer contact holes are needed, and the pattern design is more flexible.

Problems solved by technology

Accordingly, it is impossible to freely design the shapes of the conductive patterns.

Abstract

A display device comprises a first pattern disposed on a substrate and receiving a driving voltage, a second pattern disposed on the first pattern and receiving the driving voltage, an intermediate pattern disposed on the first pattern and receiving the driving voltage, a first source pattern disposed on the intermediate pattern and contacting the first pattern, the second pattern, and the intermediate pattern, a second source pattern disposed in the same layer as the first source pattern and contacting the intermediate pattern, and a third source pattern disposed on the second source pattern and contacting the second source pattern.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from and the benefit of Korean Patent Application No. 10-2020-0135464, filed on Oct. 19, 2020, which is hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUNDField[0002]The present disclosure generally relates to a display device. More particularly, relates to a display device including a structure of a pixel circuit part capable of securing a degree of freedom in designing the conductive patterns.Discussion of the Background[0003]The display device includes a plurality of pixels, and each of the pixels includes a pixel circuit part and a display element electrically connected to the pixel circuit part. The pixel circuit part has a structure in which a plurality of conductive patterns are vertically stacked, and the conductive patterns are connected to each other through contact holes. In recent years, in order to improve the display quality of the display device, the cond...
