Abstract
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.
