1. A display panel, comprising:
a substrate;
an organic light-emitting layer, located on a side of the substrate, and comprising an organic light-emitting diode (OLED) pixel;
a thin film encapsulation layer, located on a side of the organic light-emitting layer away from the substrate, and comprising multiple organic thin films, each having a light-transmission portion and a non-light-transmission portion, wherein the non-light-transmission portion is filled with anti-reflective particles; and
a color filter layer, located on a side of the thin film encapsulation layer away from the substrate, and comprising a color film disposed above the OLED pixel, wherein a first projection area of the color film is formed on the substrate, a second projection area of the OLED pixel is formed on the substrate, a third projection area of the non-light-transmission portion of the organic thin film in the thin film encapsulation layer is formed on the substrate, and a fourth projection area is formed by an area in the first projection area after an intersection area of the first projection area and the second projection area is removed, and wherein the fourth projection area is covered by the third projection area,
wherein the color filter layer further comprises a black matrix disposed between adjacent color films, a contact surface of the black matrix and the color film is an inclined slope surface, and a first slope surface formed by an end surface of the black matrix is away from the color film as a distance between the black matrix and the substrate increases; and
wherein the organic light-emitting layer further comprises a pixel definition layer for defining an area where the OLED pixel is located, a contact surface of the pixel definition layer and the OLED pixel is an inclined slope surface, and a second slope surface formed by an end surface of the pixel definition layer is away from the OLED pixel as a distance between the pixel definition layer and the substrate increases, and wherein the first slope surface is parallel to the second slope surface.
