Abstract

A pixel structure, a display device having the pixel structure and a manufacturing method of the pixel structure are disclosed. The pixel structure comprises: a first insulation layer; a luminescent unit disposed on the first insulation layer and comprising a first electrode layer, a luminescent layer and a second electrode layer; a pixel defining layer configured for defining a pixel aperture, in which the luminescent unit is disposed; and a reflective assembly disposed around the pixel defining layer so as to reflect light entering the pixel defining layer from the luminescent layer to exit from an exit surface of the pixel structure. The reflective assembly is provided to reflect the light entering the pixel defining layer from the luminescent layer, so as to exit from the exit surface of the pixel structure. As a result, the light beams entering the pixel defining layer may be converted into effective beams for the pixel structure, thereby improving the display effect and reducing light dissipation.
