Display panel and display device

A display panel, comprising:

• a first substrate, a second substrate, and a photo spacer disposed between the first substrate and the second substrate, the first substrate and/or the second substrate comprising a light shielding layer having a plurality of apertures, and an orthographic projection of the light shielding layer on the first substrate covering at least a portion of an orthographic projection of the photo spacer on the first substrate;
• wherein the first substrate comprises a first base and a first alignment layer disposed on one side of the first substrate which faces towards the second substrate, the first alignment layer comprises a first portion and a second portion, the second portion surrounds around the first portion, one end of the photo spacer is connected to the second substrate, an other end of the photo spacer corresponds to the first portion, and a distance between the first portion and the second substrate is different from a distance between the second portion and the second substrate;
• wherein the first substrate comprises a plurality of metal layers disposed between the first base and the first alignment layer, and one of the plurality of metal layers which is closest to the first alignment layer is a first metal layer, wherein the first metal layer overlaps the first portion and the second portion in a direction perpendicular to the first base;
• wherein a distance between the first portion and the second substrate is greater than a distance between the second portion and the second substrate.

A display device, comprising a housing and a display panel, wherein the housing comprises an accommodating space, and the display panel is disposed in the accommodating space, wherein the display panel comprises a first substrate, a second substrate, and a photo spacer, the photo spacer is disposed between the first substrate and the second substrate, the first substrate and/or the second substrate comprise a light shielding layer having a plurality of apertures, and an orthographic projection of the light shielding layer on the first substrate covers at least a portion of the orthographic projection of the photo spacer on the first substrate;

• wherein the first substrate comprises a first base and a first alignment layer disposed on one side of the first substrate which faces towards the second substrate, the first alignment layer comprises a first portion and a second portion, the second portion surrounds the first portion, one end of the photo spacer is connected to the second substrate, an other end of the photo spacer corresponds to the first portion, and a distance between the first portion and the second substrate is different from a distance between the second portion and the second substrate;
• wherein the first substrate comprises a plurality of metal layers disposed between the first base and the first alignment layer, and one of the plurality of metal layers which is closest to the first alignment layer is a first metal layer, wherein the first metal layer overlaps the first portion and the second portion in a direction perpendicular to the first base;
• wherein the distance between the first portion and the second substrate is greater than the distance between the second portion and the second substrate.
