Patent ID: 7580098

Claim:
A display device including a transmission area and a reflection area, comprising: a first substrate; a phase-invariant layer that is formed on the first substrate and reflects light, causing no change in the polarization state of the light; a transparent electrode formed on the first substrate; a reflective electrode formed on a portion of the transparent electrode; a second substrate that is opposite to the first substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a first optical retarder and a second optical retarder, each being attached to a respective outer surface of the first and second substrates; and a first polarizer and a second polarizer, each being attached to a respective outer surface of the first and second optical retarders, wherein the reflection area comprises an area disposed on and under the reflective electrode and the transmission area comprises an area disposed on and under the partial transparent electrode without the reflective electrode thereon, and wherein the phase-invariant layer is formed at the reflection area.
