An electronic device includes a first module and a second module stacked upon the first module in a stacking direction. The first module includes a pixel substrate and a counter substrate disposed opposite to each other. The pixel substrate is defined with a plurality of pixels. The second module is disposed at one side of the first module adjacent to the counter substrate and away from the pixel substrate. The second module includes a plurality of micro-photoelectric units and a protection layer. The protection layer stacks upon the micro-photoelectric units and is disposed at one side of the second module away from the first module. Each of the micro-photoelectric units unshields one or more of the pixels in the stacking direction. Each micro-photoelectric unit includes a micro-photoelectric element, and at least one of the micro-photoelectric elements is a sensor element.
