<P>PROBLEM TO BE SOLVED: To manufacture a substrate for an electrooptical device which excels in planarity and which can be manufactured, using an easy method. <P>SOLUTION: The substrate for the electrooptical device includes: recessed parts (110), having a first refractive index and constituting a plurality of microlens surfaces which are arranged in a matrix form, in a first area (100a) on one surface; a first layer (100) having a groove part (120) formed to partially, at least, surround the first area in a second area located around the first area; and a filling layer (300), formed by filling the inside of the recessed part and the groove part with filling material having a second refractive index which is different from the first refractive index so that one surface is flat. <P>COPYRIGHT: (C)2010,JPO&INPIT |
