1. A display device, comprising a first display panel and a second display panel stacked in a first direction, wherein:
the first display panel includes a first substrate and light-emitting units on a side of the first substrate away from the second display panel;
the light-emitting units include first light-emitting units and second light-emitting units;
one first light-emitting unit includes a first light-emitting layer, and a distance between the first light-emitting layer and the first substrate in the first direction is D1;
one second light-emitting unit includes a second light-emitting layer, and a distance between the second light-emitting layer and the first substrate in the first direction is D2, wherein D1>D2; and
the second display panel includes a reflective surface on a side of the first substrate away from the light-emitting units, wherein:
the first display panel further includes an array layer between the first substrate and the light-emitting units;
the array layer includes a first film layer; and
a thickness of a portion of the first film layer overlapping the first light-emitting units is larger than a thickness of another portion of the first film layer overlapping the second light-emitting units.
