Abstract:
A liquid crystal display device, comprising:a liquid crystal cell made by disposing a first substrate provided with scanning electrodes and a second substrate provided with data electrodes in such a manner that the scanning electrodes and the data electrodes are oppositely disposed to each other with a predetermined space therebetween, and a liquid crystal layer being filled between the first substrate and the second substrate, wherein the second substrate of said liquid crystal cell is disposed on the visible side, a polarizing film is disposed on the side of each face of the first substrate and second substrate opposite the face contacting the liquid crystal layer, wherein the polarizing film disposed on the first substrate side is a reflection-type polarizing film which transmits light linearly polarized in a direction parallel to a transmission axis thereof and reflects light linearly polarized in a direction parallel to a reflection axis thereof orthogonal to the transmission axis, an auxiliary light source is provided on the side of the reflection-type polarizing film opposite the face on the first substrate side, and wherein means for reversing a magnitude relation of a voltage applied to the liquid crystal layer between the auxiliary light source being turned on and being turned off is provided.
