Pixel circuit, display screen and electronic device

According to a pixel circuit, a scan line and a data line are arranged in a cross mode with included angles of 45 degrees to 75 degrees or included angles of 105 degrees to 135 degrees, and therefore when display screens such as a circular or quasi-circular or elliptic display screen with radian are designed, the sawtooth feeling of the edge of the screen is much smaller than that of a traditional pixel circuit arrayed in a matrix mode. The invention further discloses the display screen and an electronic device.
