1. A display panel, comprising an array substrate, wherein the display panel comprises:
a first substrate;
a first insulating layer disposed on the first substrate;
a second insulating layer disposed on one side of the first insulating layer away from the first substrate;
a first transparent insulating layer disposed between the first insulating layer and the second insulating layer, and in direct contact with at least a portion of the first insulating layer and at least portion of the second insulating layer; and
an opposite substrate disposed corresponding to the array substrate, the opposite substrate comprising a second substrate, a transparent conductive layer, and a second transparent insulating layer, wherein the transparent conductive layer is disposed on one side of the second substrate away from the array substrate, and the second transparent insulating layer is disposed between the second substrate and the transparent conductive layer;
wherein an absolute value of a difference between a refractive index of the first transparent insulating layer and a refractive index of the first insulating layer is greater than 0.1, and an absolute value of a difference between the refractive index of the first transparent insulating layer and a refractive index of the second insulating layer is greater than 0.1;
wherein an absolute value of a difference between a refractive index of the second transparent insulating layer and a refractive index of the second substrate is greater than 0.2, and an absolute value of a difference between the refractive index of the second transparent insulating layer and a refractive index of the transparent conductive layer is greater than 0.2.
