    摘要： Provided is a process for easily producing a wire grid polarizer showing a high polarization separation ability in the visible light region and having an improved transmittance in a short wavelength region. On a light-transmitting substrate 14 having a surface on which a plurality of ridges 12 are formed, an underlayer 22, first fine metallic wires 24 and second fine metallic wires 30 are formed by a vapor deposition method satisfying the conditions (A) to (F). (A) The underlayer material was vapor-deposited on a top face 16 and a first side face 18 of each ridge 12 from a direction of an angle ¸ L . (B) The underlayer material is vapor-deposited on the top face of a first underlayer 22a and a second side face 20 from a direction of an angle of ¸ R on the opposite side to that of the condition (A). (C) ¸ L and ¸ R are from 60° to 90°. (D) The height Hma1 of the underlayer 22 is from 1 to 20 nm. (E) A metal or a metal compound is vapor-deposited on the top face of the underlayer 22 and a bottom face 28 of each groove 26. (F) The height Hma2 of each first fine metallic wire 24 and the height Hp of each ridge satisfy a relation 40 nm‰¦Hma2‰¦0.9×Hp.

    摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device where a liquid crystal display panel is uniformly transmission-illuminated and display light L has a desired chromaticity.
    SOLUTION: An illuminating means 19 includes a first light-emitting element 20 for emitting first light L1 having a first color and a second light-emitting element 21 for emitting second light L2 having a second color, and illuminates the liquid crystal display panel 18 with illumination light L3 including the first light L1 and second light L2. A polarizing member 27 reflects the illumination light L3. A detecting means 28 detects the illumination light L4 having transmitted through the polarizing member 27, and outputs chromaticity data. A controlling means 56, based on the chromaticity data, adjusts the power supplied to at least one of the first light-emitting element 20 and the second light-emitting element 21. The polarizing member 27 is formed of a wire grid polarizing plate.
