AI Technical Summary
Technical Problem
Existing display devices face limitations in transistor placement during the design of pixel circuits to achieve high resolution and low area, making it difficult to meet the requirements for high pixel density.
Method used
By adopting a pixel design approach where transistors share a gate electrode or well region, multiple transistors can be adequately arranged within the pixel region, and the size of the driving transistor can be increased through the shared structure.
Benefits of technology
High display quality of high-resolution display devices is achieved by rationally arranging transistors within the pixel area, ensuring sufficient space and driving capability.

Abstract
The present application relates to a display device. The display device includes: pixels each including a first sub-pixel, a second sub-pixel, and a third sub-pixel adjacent to each other. The first sub-pixel includes: a first drive transistor including a first well region and a first gate electrode; and a first switch transistor including a second well region and a second gate electrode. The second sub-pixel can include: a second drive transistor including a third well region and a third gate electrode; and a second switch transistor including a fourth well region and a fourth gate electrode connected to the second gate electrode. The third sub-pixel includes: a third drive transistor including a fifth well region and a fifth gate electrode; and a third switch transistor including a sixth well region and a sixth gate electrode connected to the second gate electrode.
