1. A biosensor, comprising:
a stretchable substrate,
a pixel defining layer on the stretchable substrate, the pixel defining layer including
a first pixel defining layer defining a first opening extending through a thickness of the first pixel defining layer, and
a second pixel defining layer defining a second opening extending through
a thickness of the second pixel defining layer,
a photo-detecting element at least partially in the first opening, and
a first light emitting element at least partially in the second opening,
wherein an area of the first pixel defining layer in a plane parallel to an in-plane direction of the stretchable substrate is about 2 times to about 25 times an area of the first opening in the plane parallel to the in-plane direction of the stretchable substrate.
