Abstract:
An emissive display device including LEDs, including a plurality of pixels, each including: an elementary control cell formed inside and on top of a semiconductor substrate; a first LED capable of emitting in a first wavelength range, arranged on the upper surface of the elementary control cell and having a first conduction region connected to a first connection pad of the elementary control cell; and a second LED capable of emitting in a second wavelength range, having a surface area smaller than that of the first LED, arranged on the upper surface of the first LED opposite a central region of the first LED, and having a first conduction region connected to a second connection pad of the elementary control cell via a first conductive via crossing the first LED.
