Abstract: A transparent display apparatus is provided, in which light efficiency and/or transmittance is improved. The transparent display apparatus comprises a substrate provided with a plurality of pixels having a transmissive portion and a plurality of light emitting portions emitting light of different colors, and a non-transmissive portion provided between the transmissive portion and the plurality of light emitting portions and between the plurality of light emitting portions on the substrate, wherein each of the plurality of light emitting portions includes a first sub-light emitting portion and a second sub-light emitting portion, which have the same shape and size and are spaced apart from each other, the non-transmissive portion includes a first non-transmissive portion adjacent to a short side disposed in a first direction in each of the first sub-light emitting portion and the second sub-light emitting portion and a second non-transmissive portion adjacent to a long side disposed in a second direction crossing the first direction, the short sides of the first sub-light emitting portion and the second sub-light emitting portion include a first short side connected to one side of the long side and a second short side connected to the other side of the long side, the long side of the first sub-light emitting portion includes a first long side connecting one side of the first short side of the first sub-light emitting portion with one side of the second short side of the first sub-light emitting portion and a second long side connecting the other side of the first short side of the first sub-light emitting portion with the other side of the second short side of the first sub-light emitting portion, the long side of the second sub-light emitting portion includes a first long side connecting one side of the first short side of the second sub-light emitting portion with one side of the second short side of the second sub-light emitting portion and a second long side connecting the other side of the first short side of the second sub-light emitting portion and the other side of the second short side of the second sub-light emitting portion, the first non-transmissive portion and the second non-transmissive portion are provided to satisfy A: 2B = (a + b): (c + d + e), where 'A' is a length of the long side of the first sub-light emitting portion, 'B' is a length of the short side of the first sub-light emitting portion, 'a' is a length of the first non-transmissive portion in the second direction, which is adjacent to the first short side of the first sub-light emitting portion, 'b' is a length of the first non-transmissive portion in the second direction, which is adjacent to the second short side of the first sub-light emitting portion, 'c' is a length of the second non-transmissive portion in the first direction, which is adjacent to the first long side of the first sub-light emitting portion, 'd' is a length of the second non-transmissive portion in the first direction, which is adjacent to the second long side of the first sub-light emitting portion or the first long side of the second sub-light emitting portion, and 'e' is a length of the second non-transmissive portion in the first direction, which is adjacent to the second long side of the second sub-light emitting portion.
