A liquid crystal display device including: a liquid crystal layer; a liquid crystal alignment film in contact with the liquid crystal layer; a first substrate and a second substrate which are disposed so as to face each other with the liquid crystal layer sandwiched therebetween; a plurality of pixel electrodes arranged in a matrix on a surface, facing the liquid crystal layer, of the first substrate; and a counter electrode formed on a surface, facing the liquid crystal layer, of the second substrate. In the liquid crystal display device, a black matrix covering at least portions between the pixel electrodes is formed over the surface of the first substrate, facing the liquid crystal layer; the black matrix is formed in a taper shape having a taper angle .theta. smaller than 90 degrees; and the liquid crystal alignment film provides a pretilt angle larger than one-half of the taper angle .theta..
