    Abstract: A display device includes a pixel defining layer including a light emitting opening defined therein, a barrier wall layer on the pixel defining layer and including barrier walls spaced apart from each other and defining a barrier wall opening of the barrier wall layer which is between the barrier walls, the barrier wall opening overlapping the light emitting opening of the pixel defining layer, a light emitting element overlapping the light emitting opening of the pixel defining layer. and a spacer which is on a barrier wall among the barrier walls and spaced apart from the light emitting opening and the barrier wall opening. The barrier wall which has the spacer thereon defines a blocking opening of the barrier wall which surrounds the spacer.

    Abstract: A mask replacement method includes providing the mask assembly including a frame including an opening, a first mask disposed on the frame, and first welding portions overlapping the first mask in a plan view, removing the first mask from the frame, and forming a second mask and second welding portions overlapping the second mask in a plan view on the frame on which the first welding portions are disposed. The first welding portions may be spaced apart from the second mask, and the first welding portions and the second welding portions may be arranged in a direction.

    Abstract: A display device includes a light-emitting element layer and an encapsulation layer disposed on the light-emitting element layer. The encapsulation layer includes a first inorganic film having a first refractive index at a wavelength between about 380 nm and about 500 nm, the first refractive index being between about 1.5 and about 1.7, a second inorganic film disposed on the first inorganic film and having a second refractive index at a wavelength between about 380 nm and about 500 nm, the second refractive index being between about 1.5 and about 1.7, and an organic film disposed between the first inorganic film and the second inorganic film, and having a third refractive index at a wavelength between about 380 nm and about 500 nm, the third refractive index being between about 1.5 and about 1.7. Accordingly, the display device including the encapsulation layer with the high light transmittance may have the high light emission efficiency.

    Abstract: A display device includes a pixel defining layer, a barrier wall that is disposed on the pixel defining layer and in which a barrier wall opening and a groove spaced apart from the barrier wall opening are defined, a light-emitting element including an anode, an emission pattern, and a cathode that is disposed in the barrier wall opening and that contacts the barrier wall; and a lower encapsulation pattern disposed on the light-emitting element and the barrier wall. The first groove surrounds the barrier wall opening in a plan view. An inner portion of the lower encapsulation pattern is disposed in the barrier wall opening and the groove, and an outer portion of the lower encapsulation pattern defines a spacing region between the barrier wall and the outer portion of the lower encapsulation pattern.
