Abstract

A LCD device includes a LCD unit and a front light unit disposed in front of the LCD unit. The front light unit has a transparent electrode, an organic EL layer and a patterned non-transparent electrode. The non-transparent electrode has a mesh structure for defining light emission areas and transparent areas of the organic EL layer, which are arranged alternately. The light emitted by the light emission areas irradiate the LCD unit. The light reflected by reflective members of the LCD unit passes through the transparent areas of the organic EL layer and reaches to the viewer.
