Abstract:
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.
