Abstract
The invention is directed to a higher contrast in a display device having a lighting device as a front light. A lighting portion is attached to a reflective liquid crystal display portion. A first transparent substrate and a second transparent substrate made of a glass substrate etc. are attached to each other with a sealing layer coated on those peripheral portions therebetween. The back surface of the first transparent substrate is attached to the reflective liquid crystal display portion, and an organic EL element is formed on the front surface of the first transparent substrate. The organic EL element is sealed in a space surrounded by the first transparent substrate, the second transparent substrate, and the sealing layer. The organic EL element is formed in a region corresponding to a pixel region of the reflective liquid crystal display portion. A desiccant layer is formed on the front surface of the second transparent substrate.
