Shielding pattern layer has lap with filter unit when each filter unit of interval.This lap has been compared tangible projection with peripheral part, and this projection is one of reason that causes LCD alignment state confusion.Because this projection amount (rising height) becomes the key factor that influences the display panels quality, therefore, when research and development and production, need carry out strict management and control to it.
The projection amount of shielding pattern layer and filter unit lap is relevant with the thickness and the lap of shielding pattern layer.Generally, lap increases, and projection amount also increases thereupon; Otherwise lap reduces, and projection reduces the most at any time.But lap is too small, causes light leakage phenomena easily.In addition, projection amount is also relevant with process conditions, material etc.Therefore, in order to control this projection amount, to improve the quality of display, in research and development and production run, mutual relationship (related coefficient) between frequent observation filter unit of all kinds of needs and the shielding pattern layer between lap and the projection amount, this is the important content of colored filter qualitative control.
In order to record this related coefficient, in present technology, generally in the exposure process that forms red filter unit, green filter unit and blue filter unit, specially be offset the contraposition amount of light shield, produce lap continually varying polylith substrate, then the different polylith substrate of lap is measured, obtained the related coefficient between the lap and projection amount between filter unit of all kinds and the shielding pattern layer.
But traditional this method need be made the polylith substrate, and its cost is higher.On the other hand, when measuring, need to replace several substrates and test, it is more to finish the needed time of test.Again on the one hand, because in the exposure process, there is certain instability in the control of light shield when fullying recover from an illness, therefore, obtains not the difference with the consistent lap of imagination sometimes, causes the incorrect of test data.
Summary of the invention
Problem based on the existence of above-mentioned background technology, the object of the present invention is to provide a kind of colored filter that is used to test, in the present invention, only need a substrate, can finish the related coefficient between lap and the projection amount between each color filtering optical layer and the shielding pattern layer.
