Abstract
A liquid crystal display panel formed by using a TFT substrate and a color filter substrate is polished to decrease the thickness thereof so that it can be curved. The liquid crystal display panel and various optical sheets are sandwiched between a frame forming a curved surface and a light guide plate forming a curved surface, to thereby form a curved surface. An upper polarizer plate and a lower polarizer plate are, respectively, sandwiched between the surface cover and the liquid crystal display panel, and between the liquid crystal display panel and the optical sheet, and are not adhered or are partly adhered to the liquid crystal display panel.
