Luminous intensity distribution control device and display having the same
摘要:
A liquid crystal display apparatus including: a liquid crystal display element having a liquid crystal layer between a couple of substrates; a backlight apparatus arranged at one side of the couple of substrates; a polarizer arranged between the liquid crystal display element and the backlight apparatus; a luminous intensity distribution control element arranged at the other side of the couple of substrates; an analyzer arranged between the liquid crystal display element and the luminous intensity distribution control element, wherein the luminous intensity distribution control element comprises a transparent base member, a plural lenses arranged on the transparent base member, and a light absorbing layer having small opening portions substantially at focal positions of an individual lens of the plural lenses, and the transparent base member is constituted of a transparent body substantially optically isotropic or a transparent body having uniaxial optical anisotropy.
