Display panel and display device

A display panel, having an optical identification region and comprising:

• a first layer;
• a second layer, the first layer being located at a side of the second layer close to a light-exiting side of the display panel,
• wherein the first layer has at least one first light-shielding region and comprises at least one first light-transmitting hole, and the second layer comprises at least one second light-transmitting hole corresponding to the at least one first light-transmitting hole;
• wherein one of the at least one first light-shielding region and one of the at least one second light-transmitting hole at least partially overlap with each other along a direction perpendicular to a plane of the display panel;
• wherein the display panel further comprises at least one of a color filter layer or an array layer;
• and
• wherein the color filter layer comprises the first layer, and the array layer comprises the second layer.

A display panel, having an optical identification region and comprising:

• a first layer;
• a second layer, the first layer being located at a side of the second layer close to a light-exiting side of the display panel;
• and
• a display layer below the first layer and above the second layer, wherein the display layer comprises light-emitting elements;
• wherein the first layer has at least one first light-shielding region and comprises at least one first light-transmitting hole, and one of the at least one first light-shielding region surrounds one of the at least one first light-transmitting hole;
• wherein the second layer comprises at least one second light-transmitting hole corresponding to the at least one first light-transmitting hole;
• and
• wherein one of the at least one first light-shielding region surrounding one first light-transmitting hole and one of the at least one second light-transmitting hole corresponding to the same first light-transmitting hole at least partially overlap with each other along a direction perpendicular to a plane of the display panel, so that large-angle reflected light that passes through the one first light-transmitting hole successfully propagates towards an optical sensor after passing through the one second light-transmitting hole in the second layer.
