Optical modulator and method of manufacturing the same

A method of manufacturing an optical modulator comprising a first substrate, a second substrate arranged with a predetermined gap interposed between itself and said first substrate, partition wall members partitioning pixels arranged between the substrates, a liquid and a plurality of charged particles arranged at each of the pixels, and first and second electrodes arranged at each of the pixels, said method comprising:

• a step of forming the partition wall members on the second substrate;
• a step of placing the liquid and the electrically charged particles in recesses defined by the second substrate and the partition wall members;
• a step of placing a perforated member on the partition wall members to confine the charged particles in the recesses;
• and
• a step of arranging a blind member so as to close the perforations of the perforated member.

A method of manufacturing an optical modulator comprising a first substrate, a second substrate arranged with a predetermined gap interposed between itself and said first substrate, partition wall members partitioning pixels arranged between the substrates, a liquid and a plurality of charged particles arranged at each of the pixels, and first and second electrodes,

• the material of said first substrate being so selected as to bear perforations in a state of being not soaked with the liquid but close the perforations in a state of being soaked with the liquid, said method comprising:
• a step of forming the partition wall members on the second substrate;
• a step of placing the liquid and the electrically charged particles in recesses defined by the second substrate and the partition wall members;
• a step of placing the first substrate in a state of bearing perforations on the partition wall members to confine the charged particles in the recesses;
• and
• a step of closing the perforations as a result of causing the first substrate placed on the partition walls to be soaked with the liquid.
