Abstract
A liquid crystal display apparatus and a method of manufacturing wherein the liquid crystal display apparatus includes a pair of substrates, a liquid crystal layer interposed between the pair of substrates, plural electrodes formed on at least one of the pair of substrates, a passivation layer formed on the plural electrodes and having concave portions, a thin film having low wettability formed on the passivation layer, and an insulating layer formed on the thin film having low wettability. The method includes the steps of irradiating light onto the thin film through a mask, and applying a solution containing organic high polymers so as to form the insulating layer at the concave portions of the passivation layer.
