Abstract:
A driver circuit of a display device having display pixels arranged in a matrix on a substrate, the driver circuit comprising:buffer thin film transistors of a scan signal driver circuit for supplying a scan signal to the display pixels; and sampling thin film transistors of an image signal driver circuit for supplying an image signal to the display pixels, wherein channel width directions of the buffer thin film transistor and the sampling thin film transistor are identical with each other; a plurality of the sampling thin film transistors whose channel width direction is identical with the extending direction of the image signal driver circuit are arranged in parallel in the direction away from the display pixels to make up one unit, a plurality of the units are arranged in the extending direction of the image signal driver circuit, and each sampling thin film transistor located closest to the display pixels is included in a separate unit.
