Liquid crystal panel with reducing means, manufacturing method therefor and projection display apparatus using the same

A liquid crystal projection display comprising:

• a light source operable to emit an incident light;
• a liquid crystal panel for light-modulating the incident light emitted by said light source in accordance with an image to be displayed, said liquid crystal panel comprising:
• a first substrate;
• pixel electrodes in a matrix pattern on said first substrate;
• a second substrate;
• a transparent counter electrode on said second substrate;
• an ultraviolet reducing portion on one of said first and second substrates in a pattern substantially corresponding to said matrix pattern of said pixel electrodes;
• and a polymer dispersion liquid crystal layer sandwiched between said first and second substrates for forming optical images as changes in a state of light scattering by said liquid crystal layer;
• wherein said ultraviolet reducing portion has a transmittance of 30% to 70% for light less than 400 nms and is transparent for visible light greater than 400 nms;
• and
• a projection arrangement for projecting light modulated by said liquid crystal panel.
