Abstract
A display panel includes a base substrate, a driving circuit, and a roof layer defining a cavity. A color filter is disposed on the base substrate to at least partially cover the driving circuit. The color filter is disposed at least on a pixel area and includes a depression positioned at least partially within a circuit area. A black matrix is disposed upon the depression of the color filter. The black matrix being upon the depression allows an inlet portion of the cavity to remain greater than a certain cross-sectional area.
