Abstract: Glass plates for reinforcement are attached over an entire surface of a display region on a display surface side and its opposite side of a liquid crystal panel 30 to increase performance of a loading resistance to an impact from an outside or pressing force, whereby the liquid crystal panel 30 is allowed to be thin. Specifically, there is provided a display device including: the liquid crystal panel 30 which includes two transparent substrates sandwiching liquid crystals therebetween and an optical film placed on at least one of outer surfaces of the two transparent substrates; a first glass plate which is attached on a display surface side of the liquid crystal panel 30 through a first adhesive made of an optical adhesive or a translucent bonding sheet; and a second glass plate which is attached on a rear surface side of the liquid crystal panel 30 through a second adhesive made of the optical adhesive or the translucent bonding sheet.

Abstract: There is provided a color display unit having a wide range of color reproduction and low power consumption, with a simple structure, and without causing element deterioration. The display unit comprises light source means for generating blue light, a color conversion layer having a red color region for converting the blue light generated by the light source means to red light, a green color region for converting the blue light to green light, and a blue color region for transmitting the blue light as is, arranged on a flat surface, and a pixel switch structure for turning the blue light ON or OFF for each of the red color region, green color region and blue color region in response to an image signal.

Abstract: A liquid crystal device comprises a liquid crystal cell having a liquid crystal material sandwiched between a pair of substrates, the liquid crystal material having a retardation less than 1 .mu.m, a polymer film comprised of an optically anisotropic substance disposed on one of the substrates opposite the liquid crystal material, a color polarizing plate disposed on the polymer film opposite the one substrate, and a polarizing plate disposed on the other of the substrates opposite the liquid crystal material. The liquid crystal material preferably comprises a super twisted nematic liquid crystal material, and the color polarizing plate preferably comprises a red, green or blue polarizing plate.
