    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.

    Abstract: A liquid crystal display (LCD) panel is provided. The LCD panel includes a first sub-sealant and a second sub-sealant arranged in a region where a gate driver on array (GOA) circuit is placed. The first sub-sealant is closer to a display region than the second sub-sealant. Material of the first sub-sealant has stronger adhesion than material of the second sub-sealant. The material of the first sub-adhesive has lower water resistance than the material of the second sub-sealant.
