An electroluminescence display apparatus, comprising:
- a first substrate;
- a second substrate facing the first substrate;
- a light emitting layer on the first substrate between the first and second substrates;
- an encapsulation layer on the light emitting layer;
- a buffer layer on an inner surface of the second substrate facing the first substrate;
- a color filter layer including a first color filter and a second color filter on the buffer layer;
- and
- a dam structure bonding the first substrate and the second substrate at edges of the first substrate and the second substrate,
- wherein an elastic modulus of the buffer layer is smaller than an elastic modulus of the encapsulation layer such that the buffer layer absorbs pressing so that the encapsulation layer and the light emitting layer are not pressed, and
- wherein the buffer layer is spaced apart from the dam structure.
