Reflective display device

摘要

The reflective display device includes: a cell having: a display surface; a rear surface; side surfaces; and an interior space; a partition in a shape having radial extension dividing the rear surface into N regions; N rear electrodes respectively provided for the N regions on the rear surface; first side electrodes disposed on a display surface side and second side electrodes disposed on a rear surface side; N display-side electrodes separated by a separator zone in a shape having radial extension; a dielectric layer covering the N rear electrodes; polar liquid portions of N colors respectively disposed in N portions in the interior space; and polarity fluid placed within the interior space. A center of the partition matches with a center of the separator zone. A direction of the radial extension of the partition is different from that of the separator zone.

1. A reflective display device comprising:
a cell having:
a display surface;a rear surface facing the display surface;side surfaces positioned between the display surface and the rear surface; andan interior space defined by the display surface, the rear surface, and the side surfaces; a partition in contact with the rear surface and the side surfaces, the partition having height smaller than a gap between the display surface and the rear surface and being in a shape having radial extension dividing the rear surface into N regions; a rear electrode respectively provided, for the N regions on the rear surface; a first side electrode disposed on a display surface side and a second side electrode disposed on a rear surface side, both the first side electrode and the second side electrode being provided for each of N regions of the side surfaces respectively adjacent to the N regions of the rear surface; N display-side electrodes transparent to visible light, the display-side electrodes being disposed on the display surface and separated by a separator zone in a shape having radial extension; a dielectric layer covering the N rear electrodes, the N display-side electrodes, and the first side electrode and the second side electrode in each of the N regions of the side surfaces; polar liquid portions of N colors respectively disposed in N portions in the interior space divided by the partition; and polarity fluid placed within the interior space, wherein when viewed from the display surface side, a center of the partition. in the shape having the radial extension and a center of the separator zone in the shape having the radial extension match with each other, and a direction of the radial extension of the partition is different from a direction of the radial extension of the separator zone.
