Optical modulating dispaly device and production method therefor and display apparatus mounting the optical modulating display device thereon

An optical modulating/displaying device including at least:

• a first and second substrates forming a pair, wherein at least the first substrate is constituted so that light propagates therein;
• a light source provided in the vicinity of first side end of the first substrate;
• a multilayer structure sandwiched between the first and second substrates, which includes a low refraction layer being lower in refractive index than the first substrate and further being in direct contact with the first substrate, a first transparent electrode layer, a first insulating layer, a charged fine particle filled layer, a second insulating layer, and a second transparent electrode layer;
• and
• a reflection structure for reflecting at a right angle, or nearly right angle, to the boundary surface at least a part of light entering in an oblique direction from the first substrate at an opposite side to the low refraction layer with reference to the first substrate:
• wherein a boundary surface between the first substrate and the low refraction layer causes total reflection of light entering into the boundary surface in an oblique direction.
