A substrate inspection apparatus includes: an image sensor which obtains first image data of a first substrate and second image data of a second substrate; and a processor which obtains synthetic image data by using the first and second image data, where the processor obtains first first spot information and first non-spot information of a first first spot area and a first non-spot area on the first substrate, based on the first image data, obtain first second spot information and second non-spot information of a first second spot area and a second non-spot area on locations on the second substrate corresponding to locations of the first first spot area and the first non-spot area on the first substrate, based on the second image data, and obtain the synthetic image data by using the first first spot information, the first second spot information and the first and second non-spot information.

A method of determining crystallinity may include acquiring a Raman spectrum of each of samples that are crystallized, determining a first sample that exhibits a first Raman spectrum having a first Raman intensity that is largest among the Raman spectra, as an optimal sample, and determining a second sample that exhibits a second Raman spectrum having a second Raman intensity that is within a range from the first Raman intensity based on the first Raman intensity, as a first normal sample.

An organic light-emitting diode includes: a first electrode layer disposed on a base substrate; a second electrode layer disposed above the first electrode, and opposed to the first electrode; a emitting layer disposed between the first electrode layer and the second electrode layer, and including an inorganic material; a hole transport region disposed between the emitting layer and the first electrode layer; a first electron transport region disposed between the emitting layer and the second electrode layer; a interlayer disposed between the emitting layer and the first electron transport region, and having a lowest unoccupied molecular orbital (LUMO) energy level higher than that of the second electron transport region; and a second electron transport region disposed between the emitting layer and the interlayer, and contacting the emitting layer.
