Optical modulation apparatus

摘要

An optical modulation device includes: a first substrate having thereon a high-resistivity film having a sheet resistivity of 103 OMEGA / &squ& or above and a plurality of scanning electrode lines having a sheet resistivity of 102 OMEGA / &squ& or below and electrically connected to the high-resistivity film; a second substrate having thereon a plurality of data electrodes; and an optical modulation material disposed between the first and second substrates. At least one of the first and second substrates has thereon a pair of color filters of the same color disposed on both sides of at least one of the scanning electrode lines. The difference in height betwen the high-resistivity film and the scanning electrode lines is less than 1000 ANGSTROM .
