Abstract
A pressure sensor is disclosed. The pressure sensor includes a common electrode, sensitized electrodes, mountain-shaped pressure-sensitive layers, and thin-film transistors. The common electrode is formed as a layer. The sensitized electrodes are arranged in a matrix opposing the common electrode. The mountain-shaped pressure-sensitive layers are respectively formed over the sensitized electrodes on a side close to the common electrode. The thin-film transistors are disposed to correspond to the sensitized electrodes on sides of the sensitized electrodes opposite to the common electrode. A distance between the sensitized electrodes and an outer edge of a contact surface at which the common electrode and the mountain-shaped pressure-sensitive layers contact gradually becomes narrower when, due to pressing force applied to the common electrode toward the mountain-shaped pressure-sensitive layers and the sensitized electrodes, the contact surface expands outward from central portions of the mountain-shaped pressure-sensitive layers when viewed in plan.
