Abstract
A liquid crystal display device of the present invention has a structure in which vertically aligned liquid crystal is sealed between a TFT substrate and a CF substrate. Pixel electrodes in which slits are provided are formed on the TFT substrate, while cell gap holding spacers and domain defining projections are formed on the CF substrate. For example, positive type photoresist is coated on a common electrode. Then, first exposure is executed by using a mask for light-shielding spacer forming regions and projection forming regions, and then second exposure is executed by using a mask for light-shielding the spacer forming regions. Then, the photoresist is developed. Accordingly, the spacers and the projections, each having a different height, can be formed simultaneously.
