Abstract: A color filter substrate and an organic light-emitting display panel are disclosed. The color filter substrate is rectangular and has an upper side, a lower side, a left side, and a right side, wherein, the lower side corresponds to a driving chip of the organic light-emitting display panel. The color filter substrate includes a light-shielding layer defined with a plurality of light-transmitting holes arranged in an array, and from the upper side to the lower side, openings of the light-transmitting holes are gradually smaller. The present disclosure allows an aperture ratio of the light-shielding layer to be gradually reduced from the upper side that is away from the driving chip to the lower side that corresponds to the driving chip. Therefore, an area of the organic light-emitting display panel having uneven chroma and brightness can be compensated, thereby improving uniformity of the chroma and brightness.
