A positive hole transporting layer (,) is formed on an ITO film so as to form a substrate (,). A light emission organic material (,) is formed on the front surface of a convex protrusion portion (,) of a metal sheet (,). The front surface of the positive hole transporting layer (,) and the convex protrusion portion (,) are clamped with a glass plate (,). Laser light is radiated to the interior of the convex protrusion portion (,) through a shielding plate with an opening portion whose size corresponds to the size of the convex protrusion portion (,). The light emission organic material formed on the front surface of the convex protrusion portion (,) sublimates and transfers to the positive hole transporting layer (,). These steps are performed for areas of three color light emission devices.

Color organic EL display and fabrication method thereof

KrF excimer laser beam is selectively irradiated to a resist film. At this time, an incident light (KrF excimer laser beam) is reflected at the surface of an antireflection film to be a first reflected light, and is reflected at the surface of a film to be patterned to be a second reflected light. A standing wave is obtained by interference between the incident light and the first and the second reflected light. A light intensity of this standing wave has extreme maximum and extreme minimum appearing alternately, and a pair of extreme minimum and extreme maximum is across the first interface. A reflection index of the first reflected light is a range of 10 to 20%. Also, the thickness of the antireflection film is adjusted so that the extreme maximum of the pair is located in the resist film and the extreme minimum of the pair is located in the antireflection film.

An EL device is provided by a method by forming a plurality of stripes of a first transparent electrode on a transparent substrate extending in one direction of the substrate, forming a plurality of stripes of an insulating partition wall on said first electrode in a direction perpendicular to said first electrode stripes, forming an organic layer and a second electrode in sequence on the partition wall stripes, adhering a sealing glass cap so as to cover all of the above layers and evacuating the inside of said sealing glass cap, and irradiating a laser light from the outside of the sealing glass cap toward the partition wall stripes so as to separate the second electrode to form a divided groove on the partition wall. Since the separation of the second electrode by fusion is carried out in a vacuum, so that the chips of metal evaporated by the photo-ablation stick on the inside wall of the glass cap without contaminating the inside of the divided portion, which results in the prevention of shorting of the second electrode and increases the manufacturing yields in the manufacturing process.
