1. A pixel unit, comprising:

  • a first substrate;

    an intermediate stack disposed on the first substrate;

    a first light shielding layer disposed on a side of the intermediate stack adjacent to the first substrate, wherein the first light shielding layer has an opening provided therein; and

    a second light shielding layer disposed on a side of the intermediate stack away from the first substrate;

    wherein the second light shielding layer is disposed so that projection of the opening on the first substrate is located within projection of the second light shielding layer on the first substrate;

    wherein the first light shielding layer and the second light shielding layer are configured to satisfy the following formula;


    b=a+tan θ



    h+tan θ



    h, where a represents a width of the opening, b represents a width of the second light shielding layer, h represents a distance between the first light shielding layer and the second light shielding layer, θ

    1 represents an angle of a light path from an edge of the opening to an edge of the second light shielding layer on one side of the opening with respect to a normal of the first substrate, and θ

    2 represents an angle of a light path from an edge of the opening to an edge of the second light shielding layer on the other side of the opening opposite to said one side with respect to the normal of the first substrate.
