Abstract:
Included are at least one first semiconductor resistance element overlapping with one of the spacers and provided as the same layer as the semiconductor layer of the pixel transistors, at least one second semiconductor resistance element provided as the same layer as the semiconductor layer of the pixel transistors and not overlapping with any of the spacers, and a detection circuit detecting a force applied to the display region based on a midpoint voltage between the first semiconductor resistance element and the second semiconductor resistance element, and a resistance value of the second semiconductor resistance element is equivalent to a resistance value of the first semiconductor resistance element when no force is applied.
