A control section of a slideshow display device includes a display control section. The nanoscale pigment particle composition includes a benzimidazolone pigment and a sterically bulky stabilizer compound, which is a substituted pyridine derivative, associated non-covalently with the benzimidazolone pigment. The selected conductive material preferably has a hardness which is at least as great as the lowest hardness for any interlevel dielectric or passivation material employed. The Schlieren filter comprises a periodic structure of a defined period.
