Abstract
A display device according to the present invention includes a touch panel, a dielectric sheet, a frame, and a display panel. The touch panel has a touch sensor portion in the middle and a first electrode in an inner peripheral portion. Further, the dielectric sheet is closely adhered the back surface of the touch panel in its front surface. The frame has an opening in the central portion thereof and a second electrode in a marginal portion that is closely adhered the back surface of the dielectric sheet. The display panel has a display surface to display a screen image and the display surface is closely adhered the back surface of the dielectric sheet in the opening of the frame. The first electrode and the second electrode constitute a pressure-sensitive sensor that has a function to detect a pressing force when an operation element touches the front surface of the touch panel. Thus, a highly reliable display device with a touch panel can be provided in which degradation in the visibility of the display panel can be avoided and the stress occurring in the pressure-sensitive sensor is reduced.
