The liquid crystal display device includes: a liquid crystal panel in which liquid crystal is held in a cell between a first substrate and second substrate opposed to each other, an illumination device which is placed on a side of the first substrate of the liquid crystal panel; a polarization layer containing a dichroic dye that has lyotropic liquid crystal properties which is formed by application on a surface of the first substrate of the liquid crystal panel that is opposite from the liquid crystal; and a condenser lens which condenses light from the illumination device to an interior of the cell, and/or a resin layer which protects the polarization layer, which are disposed on a top surface of the polarization layer.

Liquid crystal display device and manufacturing method therefor

An object of the present invention is to provide a liquid crystal display device where there are fewer moir&#xe9; effects between lenticular lenses and the backlight. The present invention provides a liquid crystal display device where the arrangement or form of lenticular lensesvaries in waveform so that the center line of the lenses, the width of the lenses, and the height of the lenses vary in the case where light emitted from a backlightis collected into openingsfor transmitting light by means of lenticular lenses

Liquid crystal display element and liquid crystal display device having particular light collecting elements

In a transflective liquid crystal panel having an in-cell retarder, for improving a layer structure of poor adhesion, an alignment film for the retardation layer is not applied to a portion of disposing a sealing material at the main surface of a substrate of the liquid crystal panel in the step of applying the alignment film to the main surface.

Liquid crystal display device, manufacturing method thereof, and color filter substrate

A rubbing angle measuring equipment of the invention includes an light source unit, a measuring optical system, an imaging means, and an image evaluation means in which the measuring optical system is adapted such that a light from the light source unit passes by way of an illumination optical system and a polarizer to a rubbed measuring object and further passes by way of an analyzer and a focusing optical system to the imaging means, and the surface of the measuring object is focused to the imaging means, and in which image signals obtained by the imaging means are transmitted to the image evaluation means where signals having an intense periodicity in the image are detected, to measure the rubbing angle of the measuring object in a nondestructive manner, within a short period and at a high accuracy of 0.1&#xb0; or more.
