An information display device that has an EL display panel comprising: a display area having EL element pixels arranged in a matrix; a source signal line that supplies video signals to the pixels; and a gate signal line that supplies signals that control the selection/deselection of light emission from the pixels. The EL display panel has a polarization plate (32) that polarizes incident light, and comprises a coordinate detection mark (42) having properties that change the direction of the incident light. |
