Patent ID: 7948586

Claim:
A liquid crystal display device, comprising: an array substrate and a color filter substrate arranged to face each other; a liquid crystal layer provided between the array substrate and the color filter substrate; a sealing member arranged to continuously surround the liquid crystal layer and arranged to join the array substrate and the color filter substrate together; a light blocking section provided in a portion of a surface of the array substrate; and a transparent film provided on the array substrate and between the sealing member and the light blocking section; wherein the transparent film includes at least two layers made of different materials, each of the at least two layers are disposed between the sealing member and the light blocking section; and Formula (1) is satisfied where the light blocking section has a width W, the transparent film is made up of m layers (1<m), a k-th layer of the transparent film counted from a side in which the array substrate is provided has a refractive index of n k (1≦k≦m), and the k-th layer has a film thickness d k : W ≦ ∑ k = 1 m ⁢ 2 × d k × 1 n k 2 - 1 .
