摘要： Disclosed is a display device in which a redundant light-emitting element is applicable to a micro light-emitting display device to which a high-resolution panel is applied. The display device includes at least one light-emitting element; and at least one redundant light-emitting element respectively disposed in a manner corresponding to the at least one light-emitting element, wherein a first electrode of the light-emitting element is connected to a second electrode of the redundant light-emitting element via a connection electrode. Thus, even when the light-emitting element is defective, light of a corresponding color thereto is emitted normally from the redundant light-emitting element. Thus, a failure of each pixel may be lowered.

摘要： An organic light-emitting diode (OLED) display panel includes: an OLED layer; a color filter layer; and a color coordinate tuning layer disposed between the OLED layer and the color filter layer, wherein the OLED layer includes a first light-emitting portion comprising a first light-emitting layer configured to emit a first light and a second light-emitting portion comprising a second light-emitting layer configured to emit a second light. The OLED layer is configured to emit a third light produced by mixing the first light and the second light. The color coordinate tuning layer is configured to output a fourth light different from the third light. The number of all of peaks and shoulders that an EL spectrum of the fourth light has is higher than the number of all of peaks and shoulders that an EL spectrum of the third light has throughout an entire range of a visible wavelength band.
