LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is a liquid crystal display device with high luminance and contrast and excellent display characteristics. The liquid crystal display device is configured from a surface light source (20), and a liquid crystal panel (10) disposed above the surface light source and provided with a liquid crystal cell (3) and a polarizing plate stacked on a surface on the surface light source side of the liquid crystal cell. The polarizing plate is provided with a polarizing film (12) and a prism sheet (13) having the surface thereof configured from prism-shaped protrusions (13a), the prism sheet (13) is disposed such that the surface thereof configured from the prism-shaped protrusions faces the surface light source, and the light intensity distribution indicating the emission angle dependence of the light intensity of emitted light from the surface light source (20) satisfies the following (1) and (2). (1) The maximum value of the light intensity has the highest peak in the range of -80°=?<-40° or 40°<?=80°. (2) The following expression is satisfied: |?a-?b|<30° where ?a is an angle at which the maximum value of the light intensity at the peak is shown, and ?b is an angle at which a half of the maximum value of the light intensity at the peak is shown.
