Abstract:
1. A display device comprising: a touch panel including: an electric resistance between the first ferromagnetic layer of each of the sensor units and the second ferromagnetic layer of each of the sensor units being configured to change between a high resistance value and a low resistance value lower than the high resistance value in accordance with a stress applied to the sensor units, the control unit being configured to sense a change in the electric resistance in the sensor units; a first transistor provided in each of the intersection portions; a pixel electrode provided in each of the intersection portions and directly or indirectly connected to one end of each of the first transistors; and an optical layer configured to emit light or change an optical property of the optical layer including at least one of birefringence, optical rotation, scattering, diffraction, and absorption based on a charge supplied to the pixel electrode via the first transistor, wherein a gate of each of the first transistors is connected to each of the first interconnection, another end of each of the plurality of first transistors is connected to each of the plurality of second interconnections, the low resistance value is higher than an electric resistance between the one end of the first transistors and the other end of the first transistors when a portion between the one end of the first transistors and the other end of the first transistors is in a conduction state, and the high resistance value is lower than an electric resistance between the one end of the first transistors and the other end of the first transistors when a portion between the one end of the first transistors and the other end of the first transistors is in a non-conduction state.
