1. A light emitting device, comprising:
a light emitting region that includes:
a plurality of light emitting elements in a matrix arrangement; and
a plurality of first optical elements, wherein
each first optical element of the plurality of first optical elements is associated with a respective light emitting element of the plurality of light emitting elements,
the plurality of first optical elements is configured to adjust a direction of emanating light,
the plurality of first optical elements includes:
a lower layer portion that includes a color filter layer; and
an upper layer portion that includes a transparent layer,
the lower layer portion is on an incident side of the plurality of first optical elements,
the upper layer portion is on an emanating side of the plurality of first optical elements,
the color filter layer includes a concave curved surface at an interface between the upper layer portion and the lower layer portion, and
the plurality of first optical elements exposes the upper layer portion and at least a part of the lower layer portion to interface with an outside of the light emitting device.
