Abstract

A Light Emitting Diode (LED) device, particularly a micro-LED (μLED) device, suitable for a μLED display is described. The LED device comprises a LED array with a plurality of LEDs. It also comprises at least one top contact and bottom contact electrically connected to the LED array. Further, it comprises a conductive structure arranged above the LED array and the top contact, respectively, and electrically connected to the top contact. The conductive structure is, regarding each LED of the LED array, configured to absorb a first part of the light emitted by the LED, and to pass a second part of the light emitted by the LED. An emission angle (beam angle) of the passed light is thereby smaller than an emission angle of the light emitted by the LED.
