White opaque fixed films (2) in a fixed section are arranged in a two-dimensional matrix. On each fixed film (2), a cyan transparent film (3), a magenta transparent film (4), and a yellow transparent film (5) that constitute a pixel are placed. By electrostatic force, these transparent films (3, 4, 5) are driven and placed under the fixed film (2) of an adjacent pixel, thereby controlling the color of the pixel. To generate electrostatic force, the fixed film (2) and transparent film (3, 4, 5) are provided with electrodes (11) and an insulating film (12) is inserted between these two films (2; 3, 4, 5). The consecutive reversing of the polarity of both electrodes (11) enables the transparent film (3, 4, 5) to move in parallel with the fixed section (2). To achieve half tone display and no power consumption in displaying a still picture, an electrostatic mechanical latch mechanism (Ch) that stops the film (3, 4, 5) still in motion is employed. <MATH> |
