A display capable of rendering flickering hard to visually recognize, reducing power consumption and simplifying the structure of a circuit for negatively/positively reversing an image is provided. This display comprises a plurality of drain lines and a plurality of gate lines, a first pixel portion and a second pixel portion each including a subsidiary capacitor having a first electrode and a second electrode and a first subsidiary capacitance line and a second subsidiary capacitance line connected to the subsidiary capacitors of the first pixel portion and the second pixel portion respectively. The display also comprises a signal supply circuit supplying either a first signal or a second signal for negatively/positively reversing an image to the first subsidiary capacitance line of the first pixel portion when displaying the image while supplying either a third signal or a fourth signal for negatively/positively reversing the image to the second subsidiary capacitance line of the second pixel portion when reversing the image.
