1. A display panel, comprising:
a light-filtering layer;
a color film substrate;
a driving substrate;
a reflecting layer; and
a lower polarizing sheet, wherein,
the reflecting layer, the driving substrate, the light-filtering layer, and the color film substrate are stacked in sequence, and the reflecting layer is located at a side close to a light source;
the light-filtering layer comprises a black matrix with a plurality of second openings, each of the plurality of second openings is filled with one light-filtering sub-pixel, the reflecting layer defines a plurality of first openings, and each of the plurality of first openings is aligned with one second opening;
the reflecting layer comprises a plurality of film layers stacked in a stacked direction from the driving substrate to the light-filtering layer, and a refractive-index difference between any adjacent film layers is greater than or equal to 0.3; and
the lower polarizing sheet is stacked at a side of the driving substrate away from the color film substrate, and the reflecting layer is stacked between the driving substrate and the lower polarizing sheet.
 
11. The display device of claim 10, wherein the each of the plurality of first openings and each of the plurality of second openings which are aligned with each other have identical shapes, the each of the plurality of first openings comprises a first side wall, the each of the plurality of second openings comprises a second side wall parallel to and close to the first side wall, and an angle between a plane determined by a top edge of the first side wall and a bottom edge of the second side wall and the stacked direction is less than 30 degrees.
