<p>PURPOSE:To obtain a clear image without the occurrence of a Newton ring pattern and to improve transparency and durability by specifying an average particle diameter on a moving-side transparent sheet providing fine particles having adhesiveness, which can be deformed, and providing a protection film 6 on the fine particles. CONSTITUTION:A fixed side electrode 3 is given on a fixed-side transparent sheet 1, and a moving-side electrode 4 on a surface confronted with the fixed- side electrode 3 of the moving-side transparent sheet 2, and the moving-side electrode 4 and the fled-side electrode 3 are arranged at an arbitrary interval. The fine particles whose average particle diameter is more than 0.3mum and less than 100mum, which can be deformed and which has adhesiveness are provided on the moving-side transparent sheet 2, and the protection film 6 is provided on the fine particles 5. Thus, the image becomes clear without the occurrence of a Newten ring phenomenon by an input operation, and transparency and curability are improved.</p> |
