DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

A display device includes, a light emitting diode (LED) disposed on a substrate (110), and including an emission layer (EMLr, ELMg,EMLb), an encapsulation layer (400) disposed on the light emitting diode, a first layer (502) disposed on the encapsulation layer and including an opening (OP1, OP2), a light blocking pattern (BL, 503, 504) disposed in the opening and extending in a first direction (DR1), and a second layer (510) disposed on the first layer and the light blocking pattern. A refractive index of the first layer and a refractive index of the second layer are different from each other.
