Description
[technical field]
The present invention relates to a kind of black matrix", colored filter and liquid crystal indicator.
[background technology]
LCD is a kind of passive type display device, for reaching the colored effect that shows, need provide a colored filter for it, its effect is to provide colored for LCD, cooperate other assembly such as TFT (Thin Film Transistor, thin film transistor (TFT)) array and liquid crystal and show different chromatic images.
Seeing also Fig. 1, is a kind of prior art liquid crystal indicator synoptic diagram.This liquid crystal indicator 100 comprises first basic unit 14 and second basic unit 17, fills a liquid crystal layer 15 therebetween.Second basic unit, 17 bottom surfaces comprise a tft array 16.First basic unit 14 and dyed layer 12, black matrix" 13 and ITO (Indium Tin Oxide, tin indium oxide) on it layer 11 common formation colored filter (indicating).This black matrix" 13 is the distribution of ranks shape and forms many grid in this first basic unit 14, its row and column infall has interval body 18, and this interval body 18 generally is to be made by transparent material, and it is in order to support this first basic unit 14 and second basic unit 17.This dyed layer 12 comprises red (R), blue (B), green (G) three kinds of coloring units, recurring rule arrange these three kinds of coloring units in this first basic unit 14 seeing through Red light respectively, and stop the light transmission of other wavelength.This black matrix" 13 is arranged between these three kinds of coloring units, its effect is the light between three kinds of coloring units of blocking, prevent leakage of light and stop coloured material to mix that ITO layer 11 then cooperates the light of these dyed layer 12 each coloring units of control to see through number to show different colors with tft array 16.
This black matrix" 13 generally is made up of chromium and compound thereof or black resin, and its optical characteristics depends on its OD (Optical Density, optical density (OD)) value and reflectivity.OD represents the light shielding ability of black matrix", and reflectivity then refers to the light reflectance on black matrix" two sides.When black matrix" is applied to LCD, black matrix" surface and another surface relative with it of contiguous LCDs one side can be subjected to the irradiation of ambient light and LCD backlight respectively, can cause reflected light too much to produce the light interference problem if reflectivity is too high.
The OD value of black matrix" is high more and reflectivity is low more, then can make this liquid crystal display displays contrast height when it is applied to LCD, clear picture, on the contrary then display effect is poor.The black matrix" reflectivity of being made up of the black resin material is low, but the OD value is not high, and the black matrix" OD value of being made up of chromium and compound thereof is high, but reflectivity is too high.
A kind of colored filter that adopts the black matrix" of being made up of chromium and compound thereof is exposed in the United States Patent (USP) announced September 4 calendar year 2001 the 6th, 285, No. 424.See also Fig. 2, this colored filter 20 comprises a transparent glass substrate 24, a black matrix" 23, a protective seam 25 and a transparent electrode layer 21, and in addition, these colored filter 20 surfaces also are provided with a polaroid 26.This black matrix" 23 comprises one first anti-reflective film 231, one second anti-reflective film 232 and a light shield layer 233, and said modules is set in turn on this transparent glass substrate 24.
This first anti-reflective film 231 adopts different metallic compounds to make material with this second anti-reflective film 232, adopts zinc paste as first anti-reflective film 231, and then second anti-reflective film 232 adopts chromium oxide.This light shield layer 233 is made up of chromium, molybdenum, tungsten, nickel or germanium, it is different from the metal that this first anti-reflective film 231 and this second anti-reflective film 232 are adopted, the thickness of this first anti-reflective film 231 and second anti-reflective film 232 is preferably 20～60nm, and the thickness of this light shield layer 233 is preferably 50～150nm.
This patented technology is to utilize first anti-reflective film 231, second anti-reflective film 232 and light shield layer 233 each surperficial reflected light to interfere the principle that disappears mutually to reduce reflectivity, can effectively reduce the light reflectance that enters, passes through transparent glass substrate 24 from LCDs one side, but, because the light shield layer 233 of this colored filter 20 is made up of metals such as chromium, it is too high to light reflectance, when this colored filter 20 is applied to LCD, can reflection too much backlight of light shield layer 233 and produce interference phenomenon makes the display effect of this LCD be affected.
