<p>Disclosed is a display device in which deterioration in resolution may be suppressed when an image is being read, by reducing the diffusion of reflected light from a printed article, and in which a wide viewing angle may be achieved when an image is being displayed. The display device is provided with a display panel for reading and displaying image data. The display panel has a plurality of pixels provided with photo-detection elements. A plate-shaped lens member is arranged on the display surface side of the display panel. A transparent section formed of material having a high refractive index and a coloured section formed of material having a low refractive index are arranged alternately in the lens member when seen in plan view. In the cross section in the thickness direction, the transparent section has a trapezoidal shape which is wider on the display panel side, and the coloured section has a shape which is narrower on the display panel side.</p> |
