Reflective liquid crystal display apparatus

A liquid crystal display apparatus, comprising:

• a liquid crystal display element for selectively reflecting light with a certain wavelength range and thereby displaying an image;
• and
• a front light unit for projecting light through one surface of said liquid crystal display element adjacent a viewer, said light having a peak of intensity within said certain wavelength range.

A liquid crystal display apparatus, comprising:

• a liquid crystal display element having a plurality of liquid crystal layers positioned one on top the other, said liquid crystal layers selectively reflecting light with respective wavelength ranges and thereby displaying respective parts of an image;
• and
• a front light unit for projecting light through one surface of said liquid crystal display element adjacent a viewer, said light having at least one peak of intensity within any one of said wavelength ranges.

An illumination unit, comprising:

• a light source that projects light to a liquid crystal display element, said liquid crystal display element displaying an image by selectively reflecting a certain part of incident light having a certain wavelength range, said light source emitting light having a peak of intensity within said range of wavelength.

An illumination unit, comprising:

• a light source that projects light to a liquid crystal display element, said liquid crystal display element having a plurality of liquid crystal layers each reflecting certain parts of incident light having respective wavelength ranges, said light source emitting light having at least one peak of intensity within any one of said ranges of wavelength.

A liquid crystal display apparatus, comprising:

• a liquid crystal displaying element for selectively reflecting a light with a positive or negative first polarization;
• and
• an illumination unit for projecting light to one surface of said liquid crystal display element adjacent to a viewer, said projected light having a second polarization having the same polarity as said first polarization.

An illumination unit for illuminating a surface of a displaying element adjacent a viewer, comprising:

• a light source that emits light with a positive or negative polarization.
