1. A display panel comprising:
partitions between, in a cross-sectional view of the display panel, a protective layer and sensors, each of the partitions including an upper layer, a middle layer and a lower layer, a material of the middle layer being different from a material of the upper layer and a material of the lower layer, the material of the upper layer being a non-metallic material; and
light emitting units between, in the cross-sectional view of the display panel, the protective layer and the sensors,
wherein:
one of the light emitting units is configured to emit light comprised of display light and stray light,
an adjacent one of the light emitting units is configured to emit light comprised of adjacent stray light and additional stray light, and
the middle layer of one of the partitions is configured to reflect, onto one of the sensors, the stray light emitted from the one of the light emitting units and the adjacent stray light emitted from the adjacent one of the light emitting units.
