Photosensitive insulating film of organic light emitting diode (OLED)

A luminous device comprises of:

• A substrate;
• A plurality of transparent electrodes, in which a plurality of convex transparent electrodes are formed onto the substrate in ordered arrangement with an appropriate distance between each other;
• A conductive layer, which is located on the top layer of the luminous device and parallel to the substrate;
• An insulating film layer, in which it forms between the substrate and a conductive layer, by using the exposing and developing method to remove a plurality of insulating film on the central portion of transparent electrodes (but the edge portion of transparent electrode is still covered by an insulating film), it forms a plurality of insulating film layers between cavity and insulating convex, the bottom of cavity is a transparent electrode, and two side of the cavity are the insulating film material;
• A hole-transport layer, in which it forms onto a hole-injection layer in an insulating film cavity;
• A light-emitting layer, in which it forms onto a hole-transport layer in an insulating film cavity;
• and
• An electron-transport layer, in which it forms a light-emitting layer in an insulating film cavity, through the composition described above it forms a luminous device.
