Title:
OPTICAL MEMBER
Document Type and Number:
Japanese Patent JP2018036586
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical member that, when used for a liquid crystal display, can make light emitted from a light source incident on a liquid crystal display panel with high efficiency.SOLUTION: An optical member 100 has a polarizing plate 10, a reflection type polarizer 20, a polarization conversion layer 30, and a prism layer 42 integrated in this order. In terms of the luminance of natural light transmitting first and second polarizers having a degree of polarization of 99.99%, when the horizontal luminance is Land orthogonal luminance is L, the polarization conversion layer satisfies L/L≥0.2.SELECTED DRAWING: Figure 1
