Organic electroluminescent device and sealing arrangement

摘要

An organic electroluminescent display OLED device formed on a transparent substrate. First electrode lines are formed on the substrate and connected to first electrode pads at opposite edges of the substrate. The organic layer is formed on the first electrode lines. Second electrode lines formed on the organic layer are connected to the second electrode pads at the other edges of the substrate and insulated form the first electrode lines. A barrier arrangement is formed to prevent sealant from spreading inwards or outwards from a sealing area where a cap 53 is bonded to the substrate, leaving the electrode pad areas exposed. The barrier arrangement is formed on either side of the sealant 52. The barriers may be formed by insulating lines 77 formed over the electrodes 61', 62' or by extensions 75 to the electrodes, or by a combination of both, one on each side of the sealant.
