Patent ID: 7268770

Claim:
A touch-input type liquid crystal display device comprising: an upper polarizer; a lower polarizer; a transparent touch panel disposed between said upper polarizer and said lower polarizer, said transparent touch panel comprising an upper optical phase difference film, a movable electrode portion, a stationary electrode portion and a lower optical phase difference film; and a liquid crystal display, wherein a space is interposed between said upper optical phase difference film and said lower optical phase difference film, wherein said transparent touch panel is disposed between said upper polarizer and said liquid crystal display, wherein said liquid crystal display is disposed between said transparent touch panel and said lower polarizer, wherein said upper optical phase difference film is capable of providing a ¼ wavelength phase delay to light, incident thereon, having a center wavelength within a visible region, wherein said movable electrode portion is disposed on a lower surface of said upper optical phase difference film, wherein said lower optical phase difference film is capable of providing a ¼ wavelength phase delay to light, incident thereon, having a center wavelength within the visible region, wherein said stationary electrode portion is disposed on an upper surface of said lower optical phase difference film, wherein an angle formed by an optical axis of said upper optical phase difference film and a polarization axis of said upper polarizer is about 45°, wherein an angle formed by an optical axis of said lower optical phase difference film and linearly polarized light to be outputted from said liquid crystal display is about 45°, wherein an angle formed by the optical axis of said upper optical phase difference film and the optical axis of said lower optical phase difference film is about 90°, and wherein an angle formed by the polarization axis of said upper polarizer and linearly polarized light to be outputted from said liquid crystal display is about 90°, wherein said touch-input type liquid crystal display device further comprises a transparent re-peel sheet adhesively bonding overall one of a member on which said stationary electrode portion has been directly formed and said liquid crystal display or all of said member, said liquid crystal display and an other member disposed between said member and said liquid crystal display.
