Abstract

Disclosed herein is a liquid crystal display apparatus, including: a liquid crystal panel having a display region for displaying an image and having a plurality of pixels disposed in the region; and a pair of first and second polarizing plates provided in an opposing relationship to each other through the display region; the liquid crystal panel including a first substrate, a second substrate opposed in a spaced relationship to the first substrate, and a liquid crystal layer sandwiched by and between the first and second substrates and oriented.

Claims (16)

1. A liquid crystal display apparatus, comprising:

a liquid crystal panel having a display region for displaying an image and having a plurality of pixels disposed therein; and

a pair of first and second polarizing plates provided in an opposing relationship to each other through said display region;

said liquid crystal panel including

a first substrate,

a second substrate,

an illuminating section adjacent to said first substrate, and

a liquid crystal layer sandwiched by and between said first substrate and said second substrate;

wherein said liquid crystal panel having a light receiving region in which a light receiving element is formed on a face of said first substrate configured to receive light advancing from said second substrate toward said first substrate,

said liquid crystal panel being configured such that said plurality of pixels modulate the light irradiated from said illuminating section to display an image in said display region, and

said pair of first and second polarizing plates and said liquid crystal layer being disposed such that light advancing from said first substrate toward said second substrate is blocked in said light receiving region,

wherein said liquid crystal panel further includes a black matrix layer formed so as to partition said pixels in the display region and block light;

said black matrix layer being formed such that an opening through which light is transmitted corresponds to the light receiving region;

said liquid crystal panel being formed such that light transmitted through the opening formed in said black matrix layer from within the light advancing from said second substrate side toward said first substrate side is received by said light receiving element; and

said liquid crystal layer being formed such that the light advancing from said first substrate side toward said second substrate side is blocked without being transmitted through the opening formed in said black matrix layer.

2. The liquid crystal display apparatus according to claim 1 , wherein said light receiving element is provided on said first substrate so as to receive the light advancing from said second substrate side toward said first substrate side through said liquid crystal layer.
