Description
Technical field
The present invention relates to a kind of display device, particularly relate to a kind of have high to the color liquid crystal display arrangement of high brightness when.
Background technology
In recent years, liquid crystal indicator makes LCD development just rapidly on the TV purposes owing to characteristics such as it is light, thin, power savings.Yet in this application, in general has high brightness, requirements such as high contrast.
And in order to promote the liquid crystal indicator high brightness, requirements such as high contrast then have many modes to be suggested successively; Japanese kokai publication hei 10-148712 communique is for example exposed the red pigment (the C.I. paratonere 177 of green onion quinone serial pigment) of the red pixel in a kind of colored filter that is applied in liquid crystal indicator, and this red pigment can be carried out miniaturization easily through mechanical treatment; And the pigment ratio of miniaturization is easier to disperse; Therefore help improving the liquid crystal indicator contrast, but the dichroism that this pigment had makes then the brightness of colored filter effectively promote; In addition; This japanese kokai publication hei 10-148712 communique also utilizes C.I. paratonere 166 and the C.I paratonere 177 in the azo condensation class pigment to mix use with yellow uitramarine, improving color characteristics, though; The combination of these three kinds of pigment improves significantly for the color reproduction zone of expansion colored filter, yet does not but have help for the lifting of contrast.
In addition; Japanese kokai publication hei 11-231516 communique, spy open the 2002-328217 communique and then disclose another kind and utilize the C.I. paratonere 254 in the diketopyrrolo-pyrrole serial pigment, because this pigment (C.I. paratonere 254) is compared with C.I. paratonere 177, near the transmitted spectrum 600nm can squint to the short wavelength; Therefore redness backlight absorbs and becomes still less; So brightness is improved, but the particle after 254 miniaturizations of C.I. paratonere, and cohesive force is too strong between its particle; Cause disperseing to be difficult for, cause contrast to be difficult to improve.
