ABSTRACT:
An LCD device includes a transparent glass plate122and thin film transistor electrodes124formed on the glass plate122. A photosensitive insulation film128is coated on the glass plate122and the thin film transistor electrodes124. The insulation film128includes transparent and reflective regions134and133which are different in thickness. Light shielding films126are positioned underneath boundaries of the transparent and reflective regions134and133. Where an optical exposure stage includes different reflection coefficient portions, the light shielding films126prevent light reflected by the exposure stage from reaching the insulation film thereby maintaining the accuracy of its patterning.
