ABSTRACT:
A process of manufacturing a liquid crystal display device of transverse electric-field type, wherein a halftone photomask which is used to form a photoresist pattern has a fully light-shielding area preventing UV irradiation of a portion of an active matrix substrate in which a thin-film transistor element is to be formed, so that the photoresist pattern includes a positive resist portion which has a first thickness and which is formed on the above-indicated portion of the substrate. The halftone mask further has a fully light-transmitting area which permits fully UV transmission therethrough to provide the photoresist pattern with a resist-free area which corresponds to a portion of the substrate in which a contact hole serving as a third connection portion connecting an external scanning-line driver circuit and a scanning-line terminal portion through a junction electrode is to be formed. The photoresist pattern also has a positive resist portion which is formed in the other portion of the substrate and which has a second thickness smaller than the first thickness. Also disclosed in a scan-exposing device used in the process is also disclosed.
