<p><P>PROBLEM TO BE SOLVED: To provide a transparent coordinate input device and a transparent composite material which suppress the reduction of visibility due to the reflection of display light, while also suppressing the generation of interference fringes in input operation. <P>SOLUTION: Many 1st ridge parts (filaments) 45 extended to one direction are formed on the upper surface of a 1st transparent substrate 32. The cross section of each 1st ridge part 45 is a projected shape forming a triangle e.g. and pairs of slopes 46a, 46b are alternately formed on the upper surface of the 1st transparent substrate 32. Many 2nd ridge parts (filaments) 47 extended to a direction making a prescribed angle, e.g. 90°, with the 1st ridge parts 45 are formed on the lower surface of the 1st transparent substrate 32. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
