A flat organic insulating layer is formed on a substrate provided with thin film transistors by coating and baking. Next, a pulse-shaped laser beam is irradiated on the organic insulating layer and a contact hole and an undulation are formed in and on the organic insulating layer by ablation. The undulation...http://www.google.es/patents/US6894747?utm_source=gb-gplus-sharePatente US6894747 - Manufacturing method for reflector, reflector, and liquid crystal display
