Multiple view liquid crystal display
View Patent ↗In a multiple view liquid crystal display, occurrence of a reverse view phenomenon and a reverse view crosstalk are suppressed. A black matrix is formed on the opposed surface of a counter substrate to a TFT substrate in a liquid crystal panel, and a parallax barrier is provided on the black matrix with a gap layer having a predetermined thickness interposed therebetween. The black matrix includes a first light blocking part disposed immediately below an opening in the parallax barrier, and a second light blocking part with a portion immediate thereabove covered by the parallax barrier. The second light blocking part includes a low refractive-index film (reverse view preventive film), having a lower refractive index than that of a liquid crystal, at the end thereof which is in contact with a pixel opening between the second light blocking part and the adjacent first light blocking part.

3. The multiple view liquid crystal display according to claim 1 , wherein a width of said second light blocking part is larger than a width of the opening in said parallax barrier.
4. The multiple view liquid crystal display according to claim 1 , wherein said gap layer is a translucent substrate as a base material of said second substrate.
5. A multiple view liquid crystal display, comprising:
a first substrate disposed with a plurality of pixel electrodes to be supplied with image signals corresponding to a plurality of images;
a second substrate arranged as opposed to said first substrate; and
a liquid crystal sandwiched between said first substrate and said second substrate, wherein
said second substrate is provided with
a black matrix as a light blocking film disposed on the opposed surface to said first substrate and having an opening that defines an area of each pixel,
a gap layer which has a predetermined thickness and is arranged on said black matrix, and
a parallax barrier as a light blocking film which is disposed on said black matrix with said gap layer interposed therebetween and separates light having passed through the openings in said black matrix into different directions, so as to separate said plurality of images and display said images in said respective different directions,
said black matrix is provided with
a first light blocking part disposed immediately below the opening in said parallax barrier, and
a second light blocking part with a portion immediate thereabove covered by said parallax barrier, and
said second light blocking part has at the end thereof a reverse-view preventive film having a lower light transmittance than that of said opening, the end being in contact with the opening between said second light blocking part and said adjacent first light blocking part.
6. The multiple view liquid crystal display according to claim 5 , wherein said reverse view preventive film of said second light blocking part is provided only at the end of said second light blocking part which is in contact with the opening between said second light blocking part and said first light blocking part adjacent thereto in a specific direction.
7. The multiple view liquid crystal display according to claim 5 , wherein a width of said second light blocking part is larger than a width of the opening in said parallax barrier.
8. The multiple view liquid crystal display according to claim 5 , wherein said gap layer is a translucent substrate as a base material of said second substrate.
9. A multiple view liquid crystal display, comprising:
a first substrate disposed with a plurality of pixel electrodes to be supplied with image signals corresponding to a plurality of images;
