Display device and method of preparing particles for use in image display of a display device

摘要

A thin display device is provided which is capable of displaying images at a lowered driving voltage in a shortened response time by causing fine particles to travel in a gaseous phase. The display device includes: a display section having upper substrate 1 and lower substrate 2 each having a thickness ranging from about 0.1 mm to about 0.5 mm, which are disposed opposite to each other; colored particles 6 having a particle diameter ranging from about 1 mum to about 10 mum packed in an air layer 7 provided in the gap between the upper substrate 1 and the lower substrate 2; and first electrode 3 and second electrode 4 formed on the underside of the upper substrate 1. The colored particles 6 used in the display device are electrostatically charged either negatively or positively and are caused to travel between the first electrode 3 and the second electrode 4 in accordance with voltage applied to the first and second electrodes 3 and 4.
