Abstract:
A liquid crystal display device comprising:a liquid crystal display panel made up by coupling a first substrate and a second substrate, having an electrode provided on respective inner surfaces thereof facing each other, with a predetermined gap provided therebetween, and by filling the gap with a liquid crystal layer; and an input panel for detecting input information with a structure made up by coupling an upper substrate and a lower substrate, both of which are transparent, each having an electrode provided on respective inner surfaces thereof facing each other, with a predetermined gap provided therebetween, wherein upon depression on the upper substrate, each of the electrode come in contact thus achieving the detecting input information effect; wherein the first substrate on a visible side of the liquid crystal display panel being disposed so as to be opposed to the lower substrate of the input panel; a double-sided adhesive layer having a surface area equivalent to that of a display region of the liquid crystal display panel is disposed between the first substrate and the lower substrate; a second retardation film, a first retardation film, and a first polarizer are disposed in that order by laminating one on top of the other from an upper substrate side of the input panel on a visible side of the upper substrate, and wherein the first retardation film is a half-wave film and the second retardation film is a quarter-wave film.
