Abstract:
1. A display device provided with a panel and a driving unit, comprising: the panel including a front substrate and a back substrate disposed to face each other with a space therebetween, partition walls disposed in the space to partition adjacent pixels into cell spaces, and colored particles enclosed in each cell space, the driving unit causing the colored particles to move within the cell space, a first electrode being provided independently in each pixel of the panel at a bottom of the cell space facing the back substrate, a second electrode, having a common electric potential in every pixel, being provided within the partition walls and closer to the front substrate than the first electrode, and the driving unit applying a voltage between the first electrode and the second electrode to cause the colored particles in each pixel to move between being gathered by the first electrode and being gathered by the second electrode, in order to change an amount of light emitted towards the front of the panel, wherein the colored particles are constituted by core particles and surface particles covering a surface of the core particles, the core particles being formed from a material that takes a positive or negative electrostatic charge.
