Abstract
The invention relates to a light-emitting device like an OLED comprising a light emission region between an anode (5) and a cathode (6). An alternating arrangement (9) of anode pads (11) for electrically connecting the anode and cathode pads (10) for electrically connecting the cathode and an encapsulation (8) are configured such that the anode and cathode pads are electrically connectable by straight anode and cathode electrical connectors (3, 4) through openings (12) of the encapsulation. The alternating arrangement of the anode and cathode pads can lead to a more homogenous electrical field between the anode and the cathode and therefore allows for an improved degree of homogeneity of light emission. More, since the alternating arrangement of the anode and cathode pads is connectable by corresponding straight connectors, the contacting of the pads can be performed technically relatively easily.
