Display device

A display device comprising:

• a base layer;
• a light-emitting element layer disposed on the base layer;
• and
• an encapsulation layer disposed on the light-emitting element layer and comprising at least one inorganic film and at least one organic film, which are alternately laminated,
• wherein the at least one organic film comprises an epoxy-based copolymer containing at least one substituent among a hydroxy ketone group, a carboxyl group, a thioether group, a sulfone group, a cyclic thiophene group, a thiadiazole group, and thianthrene group, and
• wherein the at least one organic film has a refractive index between about 1.5 and about 1.7 at a wavelength between about 380 nm and about 500 nm,
• wherein an absolute value of a difference in refractive index between the at least one organic film and the at least one inorganic film at a wavelength between about 380 nm and about 500 nm is less than or equal to an absolute value of a difference in refractive index between the at least one organic film and the at least one inorganic film at a wavelength between about 500 nm and about 780 nm.

An electronic device comprising a display device, the display device being divided into a first emission area, a second emission area and a third emission area, the display device comprising:

• a base layer;
• a light-emitting element layer disposed on the base layer and comprising first to third light-emitting elements respectively corresponding to the first to third emission areas;
• and
• an encapsulation layer disposed on the light-emitting element layer, and comprising a first inorganic film, a second inorganic film, and an organic film between the first inorganic film and the second inorganic film,
• wherein the first light-emitting element emits red light, the second light-emitting element emits green light, and the third light-emitting element emits blue light,
• wherein a planar area of the third emission area is greater than a planar area of each of the first emission area and the second emission area,
• wherein a first refractive index of the first inorganic film with respect to the blue light is between about 1.5 and about 1.7,
• wherein a second refractive index of the organic film with respect to the blue light is between about 1.5 and about 1.7, and
• wherein a third refractive index of the second inorganic film with respect to the blue light is between about 1.5 and about 1.7,
• wherein an absolute value of a difference in refractive index between the organic film and the first inorganic film wavelength between about 380 nm and about 500 nm is less than or equal to an absolute value of a difference in refractive index between the organic film and the first inorganic film at a wavelength between about 500 nm and about 780 nm, and an absolute value of a difference in refractive index between the organic film and the second inorganic film at a wavelength between about 380 nm and about 500 nm is less than or equal to an absolute value of a difference in refractive index between the organic film and the second inorganic film at a wavelength between about 500 nm and about 780 nm.
