Patent ID: 8253869

Claim:
A liquid crystal display device with a touch panel, which has a reflective display region for being irradiated with outside light and a transmissive display region for being irradiated with light emitted from a light source, at least said transmissive display region including a liquid crystal layer energizable according to a lateral electric field mode, comprising: a back-side substrate and an observer-side substrate which are disposed in confronting relation to each other; a liquid crystal layer held between said back-side substrate and said observer-side substrate; an observer-side circular polarizer disposed outwardly of said observer-side substrate; a back-side circular polarizer disposed outwardly of said back-side substrate; an observer-side compensator disposed between said observer-side circular polarizer and said observer-side substrate, the observer-side compensator reducing refractive index anisotropy of said liquid crystal layer in said reflective display region and said liquid crystal layer in said transmissive display region; and a touch panel disposed between said observer-side circular polarizer and said observer-side compensator.
