ABSTRACT:
The invention is directed to the higher contrast in a display device with a lighting device as a front light and a reflective LCD. A lighting device is disposed, being opposed to a front surface of a reflective electrode of a reflective LCD. An organic EL element layer including an anode, a cathode patterned into stripes, and an organic layer is formed in the lighting device. A region of the organic layer corresponding to the cathode serves as an emissive region. A light shield layer is formed covering the cathode. Furthermore, a diffraction grating made of an aluminum layer and having a plurality of fine slits formed by patterning is disposed on the reflective LCD, as a polarizing layer that can be formed thinner as much as possible.
