摘要：
The invention is directed to the higher contrast in a liquid crystal display device (LCD) having a lighting portion as a front light. A lighting portion is formed by interposing an organic EL layer between a transparent substrate and a transparent substrate. A light shield layer is formed covering a cathode layer of the organic EL element layer. The lighting portion is disposed above the reflective LCD. The reflective LCD has a polarizing plate, a light scattering layer, an opposing substrate, a common electrode, a liquid crystal layer, and a TFT substrate. When the refractive indexes of seven layers of an anode layer, the transparent substrate, a resin layer, the polarizing plate, the light scattering layer, the opposing substrate, and the common electrode are defined as n(1), n(2), n(3), n(4), n(5), n(6), and n(7) respectively, the relation of 1.33>n(k)/n(k+1)>0.75(k=1-6) holds.
