We report on the formation of spatially confined exciton-polaritons under electrical injection in a textured microcavity. The trapping of polaritons in the diode sample is achieved through a locally elongated GaAs microcavity with a quality factor exceeding 6000. The polaritonic resonances of traps with diameters of 10 mu m and 2 mu m are studied by angular-resolved electroluminescence spectroscopy, revealing their hybrid light-matter nature.
