To provide a light emitting device capable of promoting an efficiency of taking
out light to outside and achieving highly reliable bright image display by lower
power consumption, in a light emitting device including a plurality of pixels and
including a transistor and a pixel electrode electrically connected to the transistor
at each of the plurality of pixels, an insulating film provided below the pixel
electrode includes an opening portion an side surface of which is a curved face
at a light emitting region. Light emitted from a light emitting element is focused
by the curved face provided at the insulating film to reduce propagation thereof
in a lateral direction, the efficiency of taking out the light is promoted and
therefore, bright image display can be achieved without particularly increasing
a current amount to be injected.
