The present invention provides a liquid crystal display device which constitutes a unit pixel for color display using pixels having color filters of respective colors consisting of red, green, blue and white and is capable of achieving a suitable multi-domain effect. In a liquid crystal display device which includes red, green, blue and white color filters in respective pixels which are arranged close to each other, the inclination of extending direction of electrodes of the respective pixels is equal with respect to the respective pixels having the red, green and blue color filters and is different with respect to the pixel having the white color filter.

A manufacturing method of organic electroluminescence display device according to the present invention performs (1) a first step for forming a non-affinity region in a surface of an anode provided in each of pixels arranged on a glass substrate by exposing the glass substrate in a saturated vapor pressure of an organic solvent, (2) a second step for forming an affinity region in a central portion of the anode surface spaced from its edges by irradiating the central portion of the anode surface with ultraviolet light, and (3) a third step for forming polymer material layers which constitute an organic electroluminescent element in the each of the pixels in the affinity region by blowing off polymer material solutions onto the affinity region of the anode in the each of the pixels, in this order, to simplify entire steps in, to reduce cost for, and to improve productivity of the manufacturing process of the organic electroluminescence display device thereby.

A backlight device, which uses solid-state light emitting elements capable of emitting lights of three colors, consisting of red, green and blue, can exhibit an enhanced light utilizing efficiency, and can generate light of high uniformity in brightness and chromaticity in a display device which can obtain a display image of high brightness with a rapid response speed. The backlight device includes a reflector which has a light reflection surface, a plurality of light transmitting cylindrical light guide bodies which are mounted on the light reflection surface of the reflector in a uniformly distributed manner, and light emitting diodes capable of emitting lights of at least three colors which are mounted inside each light guide body. By performing color mixing every light guide block, it is possible to obtain a white light of high chromaticity which has a high luminous flux distribution.

A liquid crystal display device has a liquid crystal display panel and a backlight. The backlight includes plural line light sources arranged in parallel with each other, a transparent optical plate disposed on a liquid-crystal-display-panel side of the line light sources, plural minute optical controlling elements formed on a liquid-crystal-display-panel-side surface of the transparent optical plate. The plural minute optical controlling elements extend in parallel with the line light sources, and are symmetrical in a cross section perpendicular to longitudinal axes of the plural line sources, between two adjacent midplanes each of which passes midway between two adjacent ones of the plural line light sources and each of which is perpendicular to the transparent optical plate.

The present invention restricts the fluctuation of a gap among individual display devices. The display device includes two substrates which are arranged to face each other in an opposed manner with a liquid crystal material therebetween, an annular sealing material which is arranged on peripheries of the substrates, a first region which includes an image display region, and a second region which is separated from the first region by the partition member.
