Specifically, when the fourth electrode layer 31 is connected to the third electrode 223, an insulating layer may be provided to insulate the fourth electrode layer 31 from other film layers in the electroluminescent diode device 42 in order to avoid the problems such as short-circuiting or light leakage caused by direct contact of the fourth electrode layer 31 with other film layers.
Specifically, when the second electrode layer 25 is an anode layer, the first electrode layer 22 and the fourth electrode layer 31 are cathode layers, and when the second electrode layer 25 is a cathode layer, the first electrode layer 22 and the fourth electrode layer 31 are anode layers, and accordingly, the arrangement positions of the respective film layers can be adjusted.

In one embodiment, as shown in fig. 2, the projection of the luminescent material layer 27 onto the substrate 21 coincides with the projection of the quantum well luminescent layer 23 onto the substrate 21. By overlapping the projection of the luminescent material layer 27 on the substrate with the projection of the quantum well luminescent layer 23 on the substrate 21, the area of the luminescent material layer 27 is larger, the light emitted by the luminescent material layer is more sufficient, and the brightness of red light is improved.

Specifically, the first filtering unit 341 may be a blue color resistor, the second filtering unit 342 may be a green color resistor, and the third filtering unit 343 may be a red color resistor, so that the light emitted by the micro light emitting diode device and the electroluminescent diode device respectively emits blue light, green light and red light through the blue color resistor, the green color resistor and the red color resistor, thereby improving color purity, improving color gamut, and reducing reflectivity of the display panel.
Specifically, in order to increase the brightness of the red light, the area of the red color resistance may be larger than the areas of the blue color resistance and the green color resistance.
Specifically, in order to avoid problems such as crosstalk and light leakage, as shown in fig. 2, a black matrix 35 may be disposed between adjacent filter units, for example, a black matrix 35 is disposed between the first filter unit 341 and the second filter unit 342, and a black matrix 35 is disposed between the second filter unit 342 and the third filter unit 343.
The above embodiments are described by taking the case that the projection of the light emitting material layer on the substrate coincides with the projection of the quantum well light emitting layer on the substrate as an example, but the embodiments of the present utility model are not limited thereto, for example, the projection of the light emitting material layer on the substrate coincides with the projection of the quantum well light emitting layer on the substrate, but the width of the light emitting material layer may be increased, so that the light emitting brightness of the light emitting material layer is higher, no color resistor is required, and the thickness of the display panel is reduced.
