Front-mounted light source and display device

A display device, comprising:

• a reflective display panel, a polarizer, a second quarter-wave plate and a front-mounted light source, wherein the front-mounted light source, the second quarter-wave plate and the polarizer are all arranged at a display side of the reflective display panel, the second quarter-wave plate is between the front-mounted light source and the reflective display panel, the polarizer is arranged at a side of the second quarter-wave plate away from the reflective display panel, and a polarization direction of the polarizer is a first polarization direction;
• wherein the front-mounted light source comprises:
• a base substrate and a plurality of light-emitting elements on the base substrate;
• wherein each of the light-emitting elements comprises a light-emitting layer and a reflective layer, and the reflective layer is between the light-emitting layer and the base substrate;
• a side of at least one light-emitting element away from the base substrate is provided with a first quarter-wave plate and a polarizing layer;
• the polarizing layer is at a side of the first quarter-wave plate away from the light-emitting element and is used for transmitting polarized light of the first polarization direction and reflecting polarized light of a second polarization direction;
• and the first polarization direction intersects the second polarization direction.
