Optionally, the insulating layer 450 and the flat layer 460 can be one layer or multiple layers. For example, it can be one insulating layer 450 and one flat layer 460, or two insulating layers 450 and one flat layer 460, or one insulating layer 450 and two flat layers 460, or two insulating layers 450 and two flat layers 460, etc. Optionally, the insulating layer 450 and the planar layer 460 may be made of an organic material, such as an organic resin, a polyimide film, etc., or may be made of an inorganic material, such as silicon dioxide, silicon nitride, etc.

[0058] A filter film 1000 is provided on the side of the insulating layer 450 and the flat layer 460 away from the cathode 440. The filter film 1000 includes a light-transmitting area 100 and a light-shielding area 200. The light-transmitting area 100 includes a plurality of first color filters 110 that can transmit the first color, a plurality of second color filters 120 that can transmit the second color, and a plurality of third color filters 130 that can transmit the third color.

The first color can also be red, the second color can be blue, the third color can be green, etc. Optionally, the first color can be blue, the second color can be red, the third color can be yellow, etc. As long as the first color, the second color and the third color are superimposed, a certain degree of display function can be achieved.

[0059] Optionally, the first color film 110, the second color film 120 and the third color film 130 can be quadrilateral color films, hexagonal color films, or irregular color films; or the first color film 110 is a hexagonal color film, the second color film 120 and the third color film 130 are quadrilateral color films; or the first color film 110 is a hexagonal color film, the second color film 120 and the third color film 130 are irregular color films, etc. The areas of the first color film 110, the second color film 120 and the third color film 130 can also be set as required. As long as it satisfies that the amount of light emitted through the first color film 110, the second color film 120 and the third color film 130 is within a reasonable range. The thickness of the first color film 110, the second color film 120 and the third color film 130 is the same, that is, the thickness of the entire light-transmitting area 100 is uniform, that is, the surfaces on both sides of the entire light-transmitting area 100 are flat.

[0060] A plurality of first color filters 110, a plurality of second color filters 120 and a plurality of third color filters 130 are respectively distributed in an array on the filter film 1000. The area between the first color filter 110, the second color filter 120 and the third color filter 130 is a light shielding area 200, that is, the first color filter 110, the second color filter 120 and the third color filter 130 are separated by the light shielding area 200.

[0061] The shading area 200 includes a plurality of stacked shading layers, including at least two of a first shading layer 210 made of the same material as the first color filter 110 , a second shading layer 220 made of the same material as the second color filter 120 , and a third shading layer 230 made of the same material as the third color filter 130 .

Optionally, the thickness of the first light shielding layer 210, the second light shielding layer 220 and the third light shielding layer 230 are equal, and the thickness of the first light shielding layer 210, the second light shielding layer 220 and the third light shielding layer 230 can also be adjusted to be unequal according to actual needs. The thickness of two of the first light shielding layer 210, the second light shielding layer 220 and the third light shielding layer 230 is the same as the thickness of the first color film 110, the second color film 120 and the third color film 130.

[0063] Optionally, the plurality of light shielding layers include a first light shielding layer 210 of the same material as the first color film 110, a second light shielding layer 220 of the same material as the second color film 120, and a third light shielding layer 230 of the same material as the third color film 130. The orthographic projections of the three light shielding layers in the thickness direction completely overlap. Optionally, the thicknesses of the first light shielding layer 210, the second light shielding layer 220, and the third light shielding layer 230 are equal, and the thicknesses of the first light shielding layer 210, the second light shielding layer 220, and the third light shielding layer 230 can also be adjusted to be unequal according to actual needs. The superimposed thickness of the first light shielding layer 210, the second light shielding layer 220, and the third light shielding layer 230 is the same as the thickness of the first color film 110, the second color film 120, and the third color film 130. In this way, the thickness of the entire light shielding area 200 is uniform, that is, the surfaces on both sides of the entire light shielding area 200 are flat. The thickness of the entire light-shielding area 200 is consistent with that of the entire light-transmitting area 100 , that is, the thickness of the entire filter film 1000 is uniform and the surface is flat.

The thickness of the light shielding area 200 formed by overlapping different light shielding layers is always consistent with the thickness of the entire light-transmitting area 100. Fig.11As shown, in an optional embodiment, the first color film 110, the second color film 120 and the third color film 130 are all hexagonal in shape. The first color film 110, the second color film 120 and the third color film 130 are arranged in an array.

The area between the second color film 120 and the third color film 130 forms a light shielding area 200 where the first light shielding layer 210, the second light shielding layer 220 and the third light shielding layer 230 are superimposed. The thickness of the light shielding area 200 formed by superimposing different light shielding layers is always consistent with the thickness of the entire light-transmitting area 100. Optionally, the light shielding area 200 can be covered with the second light shielding layer 220 of the same material as the second color film 120, the first color film 110 is surrounded by the first light shielding layer 210 of the same material as the first color film 110, and the third color film 130 is surrounded by the third light shielding layer 230 of the same material as the third color film 130.
