Dyes for optical filters
Optical filters are the optical element which transmits the selected light only and does not transmit any other light. In optical filters, the specific dyes which absorb the specific light not wanted to transmit are used.
These dyes for optical filters have been applying to PDP neon-cutting filters, agricultural films, illumination sensors and others. We have full line-up of dyes having the absorption wave length range of 400 nm ～ 1100 nm.

Dyes for PDP neon-cutting filters
Plasma Display Panel (PDP) is a flat panel display device which utilizes the function of exciting and light emitting of a phosphor by ultra-violet rays generated by plasma discharge.
Though PDP has been attracted attention as a wide screen display panel, it is required to absorb other lights except ultra-violet rays generated at the plasma discharge.
In these lights to be absorbed, there are near-infrared rays having the wave length of over 850 nm and neon light at around 580 ～ 590 nm. Our dyes for PDP absorb these lights effectively and have been contributing largely as a core material for PDP.

Dyes for LCD
Liquid Crystal Display (LCD) is a flat type thin visual display terminal. The display is conducted by modulating light with utilizing the liquid crystal composition which does not emit light in itself.
To display the image, polarization filters which control light passing through and color filters which display colors are required. We have dichroic dyes in our line-up.

The display method of Liquid Crystal Display (LCD) is not the display method by emission in itself like the conventional cathode-ray tube display, but the display method by utilizing the transmittance of light. LCD has been applying widely in various fields.
Our dichroic dyes have excellent solubility to liquid crystals, contrast and clearness and have been applying widely to liquid crystal display panels, instrument panels of automobile and others.
