ABSTRACT:
On the first substrate that serves as an active-element-side substrate, pixel electrodes are formed with a flattening film interpolated in between. On the second substrate that serves as an opposing-side substrate, light-shielding films are formed into an island pattern which allows the light-shielding films to shield the respective active elements on the first-substrate side from light, and gap-controlling sections are formed into the same island pattern as the light-shielding films by exposing positive-working photosensitive resin layer that has been applied onto the entire surface of the second substrate from the back-surface side of the second substrate by using the light-shielding films as a photomask. The flattening film makes it possible to suppress the occurrence of disclination in the liquid crystal molecules. Therefore, the light-shielding films can be formed as the island pattern that only shield the active elements from light, and consequently it is possible to improve the aperture rate. Further, since the gap-controlling layer can be formed at portions other than the pixel electrodes, it is possible to avoid degradation in the contrast ratio of a liquid crystal display.
