Abstract
A display includes an antistatic circuit between a common wire and at least one of a signal wire and a scanning wire. The common wire is disposed in a non-display region, and receives a common potential. The signal and scanning wires are disposed in a display region. The antistatic circuit at least includes a first transistor having a floating control electrode, a first main electrode connected to the signal wire or the scanning wire, and a second main electrode connected to the common wire. The first transistor is provided in such a manner that a first capacitance between the control electrode and the signal wire or the scanning wire is larger than a second capacitance between the control electrode and the common wire.
Claims7
A display provided with a display region and a non-display region in contact with the display region, the display region being provided with scanning wires and signal wires arranged to intersect each other, and with pixels arranged in matrix form, the pixels each being disposed in a region defined by the scanning wires adjacent to each other and the signal wires adjacent to each other, the display comprising:
- an antistatic circuit disposed between a common wire and at least one of each of the signal wires and each of the scanning wires in the display region, the common wire being disposed in the non-display region and configured to receive a common potential and supply the common potential to a counter electrode of the display, wherein
- the antistatic circuit at least includes a first transistor, the first transistor including a floating control electrode, a first main electrode connected to one of the signal wires or one of the scanning wires, and a second main electrode connected to the common wire,
- the first transistor is provided in such a manner that a first capacitance formed between the control electrode and the one signal wire or the one scanning wire is larger than a second capacitance formed between the control electrode and the common wire, and
- a magnitude relationship between the first and second capacitances in the first transistor is defined by setting a distance between the control electrode and the first main electrode in a vertical direction, and setting a distance between the control electrode and the second main electrode in the vertical direction, in such a manner that the distance between the control electrode and the first main electrode of the first transistor in the vertical direction is shorter than the distance between the control electrode and the second main electrode of the first transistor in the vertical direction.
