Abstract
The invention provides a method for manufacturing a cholesterol LCD element and the manufactured product thereof. The method is that one side of a lower substrate is provided with a blue negative photoresist layer as an undertone layer in the way of knife coating and spin coating, so that film thickness of the undertone layer can be controlled to be uniform without the phenomenon of irregular color or the loss due to pinhole, foreign body and scratches, etc. When the LCD element is lightened, undertone regularity is good.
Description
Technical field
The present invention relates to a kind of method for making and composite thereof of cholesteric liquid crystal display element, especially a kind of method for making and composite thereof that has had the minus photoresistance of color as the cholesteric liquid crystal display element of background color layer.
Background technology
General cholesterin liquid-crystal display has the characteristic of Memorability, optical bistability for utilizing cholesterol liquid crystal, and the renewal frequency that is particularly suitable for being applied to show image is not high, and show image needs to maintain for a long time the display device under the state of use again simultaneously.Electronic products such as e-book, electronic board and personal digital assistant for example.Because cholesteric liquid crystal molecule itself has optical activity, selective light scattering, rotatory polarization dichromatism or the like optic characteristic, therefore do not need to add light polarizing film and filter again.In addition, cholesterin liquid-crystal display is reflective, directly utilize environment light source just can read, and brightness height, even picture is also very clear under the big out of doors sun, do not need to add again backlight module, totally can reduce the manufacturing cost of LCD more than 30% approximately, be applicable to outdoor large-scale electronic board more.
Because cholesterin liquid-crystal display is a color of utilizing the background color layer of external light source reflective display panel bottom, and make indicator screen present the figure or the literal of background color layer color, so the quality of background color layer can influence the display effect of display.
As shown in Figure 5, be existing cholesteric liquid crystal display element, it is that mainly the relative inner of upper and lower glass substrate 7,8 is respectively equipped with electrically conducting transparent circuit 71,81, and in 7,8 perfusions of upper and lower glass substrate cholesterol liquid crystal, again in the opposite side of lower glass substrate 8 relative electrically conducting transparent circuits 81, in the screen painting mode, printing one deck blue ink makes it form blue background color layer 9.
Yet when above-mentioned prior art was applied to liquid crystal display cells, this blueness background color layer 9 was directly to be printed in the back side that lower glass substrate 8 exposes, and is shaped in the screen painting mode.Because the inferior quality of screen printing, film thickness monitoring are difficult for., as shown in Figure 6, the liquid crystal display cells that prior art is made produces color depth 75 and the even disappearance of look shallow 76 irregular colours, causes display element to have the uneven phenomenon of local repressentation effect when lighting, in the same frame.And in the process of screen printing background color layer 9, be easy to generate pin hole 72 and foreign matter 73 adheres to, and in the module assembling process, the background color layer 9 that is positioned at the outside is easy to generate scratch 74, and therefore the disappearances such as pin hole 72, foreign matter 73 and scratch 74 that produced all can influence its display effect.
Summary of the invention
Fundamental purpose of the present invention, the inboard that is lower glass substrate is coated with the photoresistance that one deck has color, to form the background color layer, and make the controllable film thickness system of background color layer even, phenomenon that can coloured inequality, and can improve disappearances such as pin hole, foreign matter and scratch, the background color uniformity coefficient is good when allowing display element light, and has preferable display effect.
