Manufacturing method for reflector, reflector, and liquid crystal display

Abstract

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 is formed in such a way as to have four or more height levels.

1  A reflector comprising: 
 an insulating layer on a substrate, said insulating layer having an undulation forming portion that is continuous and has plural peaks separated by valleys, the peaks having at least four different heights; and    a reflective electrode on said undulation forming portion.    
   
   
       2 . The reflector of  claim 1 , wherein the valleys have at least four different heights that are different from the heights of the peaks.  
   
   
       3 . A liquid crystal display having the reflector as recited in  claim 1 .  
   
   
       4 . A reflector comprising: 
 an insulating layer on a substrate, said insulating layer having an undulation forming portion that is continuous and has plural valleys separated by peaks, the valleys having at least four different heights; and    a reflective electrode on said undulation forming portion.    
   
   
       5 . A liquid crystal display having the reflector as recited in  claim 4.
