Transparent display apparatus

A transparent display apparatus, comprising:

• a transparent substrate, having a plurality of display areas and a plurality of transparent areas;
• a first pixel array, disposed on the transparent substrate, wherein the first pixel array comprises
• a plurality of first pixels, arranged in an array along a first direction and a second direction, wherein the first direction and the second direction intersect, and each of the first pixels overlaps a corresponding display area;
• and
• a plurality of first openings, wherein each of the first openings is surrounded by a portion of the first pixels, and each of the first openings overlaps with a corresponding transparent area;
• a plurality of signal lines, disposed on the transparent substrate and are electrically connected to the first pixels;
• and
• a light leakage suppression element, comprising a plurality of light blocking structures spaced apart from each other, wherein the transparent substrate has a first side and a second side opposite to each other, the first pixels are disposed on the first side of the transparent substrate, and at least a portion of each of the light blocking structures of the light leakage suppressing element is disposed on the second side of the transparent substrate.
