Liquid Crystal Element Dark Line Reduction

A light-shielding film is introduced as an intermediary layer between adjacent pixel electrodes. This film extends from the surface of the first substrate toward the second substrate, creating a physical barrier that prevents short circuits while allowing the gap between pixel electrodes to be minimized for improved appearance. The light-shielding film acts as a mediator that resolves the contradiction by providing electrical isolation without requiring larger gaps.

The light-shielding film is strategically positioned only in specific locations where it is needed for isolation, rather than uniformly across the entire structure. The film extends from the first substrate surface toward the second substrate in regions between pixel electrodes, providing localized quality enhancement. This allows the wiring to maintain sufficient thickness for reliability while the light-shielding film prevents dark line formation in the gaps.

The light-shielding film serves as an intermediary element that decouples the relationship between gap size and dark line visibility. By introducing this film, the gap can be maintained at a larger size for ease of wiring extension and manufacturing, while the film itself blocks light leakage that would create dark lines. This resolves the contradiction by allowing both larger gaps and reduced dark line visibility through the mediating film.
