Abstract: A color-filter on array (COA) substrate and a method of fabricating the same are described. A first through hole is disposed in a first passivation layer, a second through hole is disposed in the color resist layer, and a third through hole is disposed in the second passivation layer, wherein the first through hole communicates with the second through hole, and the second through hole communicates with the third through hole to collectively form an opening. A hole diameter of the opening gradually increases from bottom to top. A part of the color resist layer is etched while the second passivation layer is etched so as to reduce a taper angle of the opening. Therefore, a relatively large impedance value impedance or disconnection is avoided when depositing a pixel electrode.
