Display panel and display apparatus

A display panel, comprising:

• a first substrate, a refractive index adjustment mechanism and a second substrate successively arranged along a light output direction,
• wherein a first black matrix is formed on the first substrate, the first black matrix comprises a plurality of first shading portions and a plurality of first openings among the plurality of first shading portions;
• a second black matrix is formed on the second substrate, the second black matrix comprises a plurality of second shading portions and a plurality of second openings among the plurality of second shading portions,
• wherein the plurality of first shading portions are configured to be arranged opposite to the plurality of second openings in the light output direction, respectively, and the plurality of second shading portions are configured to be arranged opposite to the plurality of first openings in the light output direction, respectively;
• and
• wherein the refractive index adjustment mechanism is configured to adjust an amount of light exiting from at least one of two second openings closest to a first opening from which the light is incident.
