Abstract
It is an object of the invention to provide a liquid crystal display apparatus in which the cell gap is uniform and the display quality is high, and also a method for manufacturing the same. In the liquid crystal display apparatus, a color filter side substrate in which a protrusion is formed by a black mask, and a TFT side substrate in which a recess is formed by a resin film such as an orientation film are bonded together via dispersed spacers therebetween, and a liquid crystal is filled between the substrates. In the resin film such as an orientation film, patterning is performed except a portion which is opposed to the protrusion, thereby forming the recess in the TFT side substrate. The formation of the recess prevents the cell gap from being pushed up even when the dispersed spacers are placed on the protrusion. Even in the case where the substrates are not flat, therefore, the cell gap can be maintained uniform.
