US 2017/0249916 A1 · DRIVING CIRCUIT AND DISPLAY DEVICE

Abstract

The present invention provides a driving circuit and a display device. The driving circuit is disposed on a substrate of the display device. The driving circuit includes thin film transistors (TFTs), a capacitor and clock signal lines. Each of the TFTs includes a gate, a source and a drain. The capacitor is coupled to at least one of the TFTs, and includes a first and a second electrode. The material of the first and the second electrode includes a transparent conductive material. The clock signal lines extend along a first direction. The source and the drain of at least two of the TFTs respectively extend along a second direction. The angle between the first direction and the second direction is between 80 degrees and 100 degrees. At least a partial structure of the capacitor is located in a gap between adjacent ones of the TFTs.
