Description
Technical field
The present invention relates to a kind of elastic resin plate, it is used for aniline printing, can form the alignment film of homogeneous film thickness etc. on the substrate surface of used for liquid crystal display element substrate etc.
Background technology
In the past, printing with the surface of protuberance on equably distribution be formed with the resin relief of a plurality of small protuberances, be used for the various printings of letterpress mode such as aniline printing.Especially in recent years, when making liquid crystal indicator, in order on the substrate surface of its used for liquid crystal display element substrate, to be formed for forming the alignment film of both alignment layers, the aniline printings of adopting the use resin relief by printing more.Particularly, on the electrode forming surface (substrate surface) that will be formed on used for liquid crystal display element substrate such as glass substrate by aniline printing, be extensive use of the resin relief of making of ray hardening resin by the alignment film that polyimide resin constitutes.And, use above-mentioned resin relief, printing is formed with the glass substrate of the alignment film that is made of polyimide resin, stacked in above-mentioned two polyimide resin material alignment films mode respect to one another, liquid crystal is injected in the gap of polyimide resin material alignment film, is made into liquid crystal indicator thus.
Above-mentioned alignment film for example, is to form through following operation printing.That is to say, at first, prepare resin relief, on the whole surface of printing with protuberance of this resin relief, be formed with in order to keep the uniform ditch of the amount portion of coating fluid.Above-mentioned ditch portion is by being provided with small protuberance highlightedly with uniform size and distribution density in above-mentioned printing respectively on the surface of protuberance, forming between each small protuberance at these.Then, to the coating fluid of printing, make coating fluid remain on printing with on the surface of protuberance with the whole surface coating polyimide resin of protuberance, this coating fluid is copied to the substrate surface of glass substrate, and after this duplicated, it was dry to make it the universe, remove and desolvate, fire.Thus, be formed on the above-mentioned glass substrate with the surperficial corresponding position of protuberance and the alignment film of the polyimide resin material in zone with printing.
Be formed at polyimide resin material alignment film on the glass substrate with this mode printing, be required uniform thickness.That is to say, recently, in order to realize that liquid crystal indicator has higher gray scale to show or high-contrast, alignment film itself is also required high uniformity, if above-mentioned polyimide resin material alignment film is in uneven thickness, even small varied in thickness also can produce the problem of the bad or variations in threshold voltage in gap, demonstration look generation color spot.

Summary of the invention
(inventing problem to be solved)
Yet, as mentioned above, distribute the resin relief that is formed with a plurality of small protuberances on the surface of protuberance equably when carrying out aniline printing, the problem below existing when adopting in printing.That is to say, usually, in aniline printing, be on the surface of printing machine version body (drum), resin relief to be installed, supply with coating fluid and with predetermined rotational speed and push pressure and coating fluid is copied on the above-mentioned glass substrate to it, therefore, when on the substrate surface that each small protuberance of above-mentioned resin relief is pressed onto this glass substrate with a state of contact, above-mentioned pushing pressed each the small protuberance that acts on above-mentioned resin relief.At this moment, for the printing of above-mentioned resin relief for each small protuberance of the surperficial middle body of protuberance, can bear the above-mentioned pressure that pushes by being enclosed in its each small protuberance on every side, wearing and tearing or damaged can take place in the head portion of each small protuberance hardly, but for the printing of above-mentioned resin relief for each small protuberance of the surface periphery part of protuberance, then because few or do not have fully at the small protuberance of its peripheral part, so with compare on each the small protuberance that acts on above-mentioned surperficial middle body, the bigger effect of being pressed in that pushes is arranged, the wearing and tearing or damaged easily of the top end face of each small protuberance of above-mentioned surface periphery part, weak strength, the deterioration life-span is short.And, by the printed polyimide resin material alignment film that forms of above-mentioned resin relief, compare with its middle section, can produce the phenomenon of the thickness thickening of its neighboring area.This is because following reason causes.That is to say, when the duplicating of above-mentioned coating fluid, rotation corresponding to printing machine version body, the printing that remains on above-mentioned resin relief moves to printing with the coating fluid in the surperficial middle body of protuberance and is trapped in the there with surface periphery part one side of protuberance, in this surface periphery part, the coating liquid measure increases and produces liquid and accumulate, and consequently produces the phenomenon (hereinafter referred to as " edge effect ") of thickness thickening of the peripheral part of resulting alignment film.For example should form thickness is 300～900
Alignment film, but be formed into 1200～3000 in its peripheral part
The left and right sides is thick.And, accumulate owing to partly producing liquid in above-mentioned surface periphery, thus when above-mentioned point contacts, there is bigger reaction force to put on above-mentioned surface periphery each small protuberance partly, thereby the further generation easily of above-mentioned top end face is worn and torn or is damaged.In order to eliminate such bad phenomenon, in the past, existing people attempts printing is studied with the design of the pattern form of protuberance, or waits the whole bag of tricks such as improving printing machine by the automatic adjustment of print station sweep speed or coating fluid concentration, but, be not resolved in fact as yet.
The present invention just carries out in view of situation as described above, and purpose is for providing a kind of elastic resin plate, its intensity height, and the deterioration life-span is long, and edge effect does not also take place, and also can form in the peripheral part to equate with middle body and the alignment film of thickness etc. uniformly.
In order to achieve the above object, elasticity of the present invention tree version is that a kind of coating fluid that is used for being arranged on the printed patterns of regulation Printing Department copies to the elastic resin plate that rigid plate is printed on the body and the aniline printing of printing is used, and it has adopted a plurality of recesses that will only be used to print and hold above-mentioned coating fluid to be formed on structure on the part with the corresponding above-mentioned Printing Department of above-mentioned printed patterns in discrete mode respectively.
(effect of invention)
That is to say, present inventor etc., in order to obtain the intensity height, the deterioration life-span is long, and also edge effect does not take place, also can form in the peripheral part to equate with middle body and the resin relief of the alignment film of thickness etc. uniformly, has carried out a series of research repeatedly.And, at first carried out research repeatedly with regard to the reason that produces edge effect, the result has found out because the situation of the problem that reason as described above causes, and so that when the duplicating of above-mentioned coating fluid, the printing that is trapped in resin relief with the coating fluid in the surperficial middle body of protuberance toward printing with surface periphery part one side shifting of protuberance and to be trapped in the there be that the center has carried out studying repeatedly.Consequently, think as before, use distributes equably on printing with the surface of protuberance and is formed with the resin relief of a plurality of small protuberances, coating fluid is filled in the ditch portion that is formed between above-mentioned each microspike, can not prevent moving of above-mentioned coating fluid like this, therefore, use further research repeatedly of situation with the diverse new resin plate of above-mentioned resin relief to not using above-mentioned resin relief, find if a kind ofly be used for that the printed patterns with regulation is arranged on printing and copy to the elastic resin plate that rigid plate is printed on the body 1 and the aniline printing of printing is used with the coating fluid in the Printing Department of protuberance etc., promptly, use has formed in discrete mode respectively on the part of the above-mentioned Printing Department corresponding with above-mentioned printed patterns and only has been used to print and holds the elastic resin plate of a plurality of recesses of above-mentioned coating fluid, then this elastic resin plate is originally high on intensity, its deterioration life-span is long, if and use this elastic resin plate to carry out aniline printing, edge effect can not take place then yet, can obtain the alignment film of homogeneous film thickness etc., thereby realize the present invention.
In elastic resin plate of the present invention, although in its Printing Department, be formed with a plurality of recesses, but these recesses form in discrete mode respectively, so, (that is to say, be to be pressed in the part that rigid plate is printed the Printing Department on the body when the duplicating of above-mentioned coating liquid, promptly not to be formed with the part of these recesses, non-printing), its middle body is to be connected with the peripheral part planarly.Therefore, when the duplicating of above-mentioned coating liquid, the non-printing of the Printing Department of elastic resin plate is that face is pressed in rigid plate touchingly and is printed on the body, can by the middle body of above-mentioned non-printing and peripheral part approximate equality bear this and push pressure, wearing and tearing or damaged can take place in the peripheral part of above-mentioned non-printing hardly, the intensity height, the deterioration life-span is long.And, because each recess of above-mentioned Printing Department forms in discrete mode respectively, so, when the duplicating of above-mentioned coating liquid, the coating liquid that is accommodated in above-mentioned each recess can not move to the peripheral part from the middle body of above-mentioned Printing Department, and edge effect does not take place.And, as long as by suitably setting the big or small of above-mentioned each recess and the coating liquid measure that is contained in above-mentioned each recess being controlled, to be set at by the coating liquid measure that above-mentioned each recess keeps and in the past equal maintenance dose, and just can on this peripheral part, also obtain to equate and the alignment film of uniform thickness etc. with middle body.And, for semi-transmission type (for example, has outside on rigid plate is printed the surface of body, being formed with light with the reflecting part of reflectance coating, the permeation parts that is exposing to the open air with the surface that makes rigid plate be printed body) rigid plate is printed body with keeping intact, in the part of above-mentioned semi-transmission type, though it is poor with the suitable ladder of the thickness of reflectance coating to obtain with outer light, but, elastic resin plate of the present invention, because the coating liquid that is maintained in the recess is not put movably to be duplicated, so, also can carry out good aniline printing for the part of above-mentioned semi-transmission type.
In addition,, then each recess can be formed on thick and fast in the above-mentioned Printing Department and reduce the area of above-mentioned non-printing if above-mentioned each recess is oriented to the honeycomb structure shape, do not produce apply uneven.In addition, in the present invention, the such state of said " honeycomb structure shape (the nest structure shape of so-called honeybee) " expression: above-mentioned each recess respectively on the direction of regulation by the parallel shape that is adapted to a plurality of row, and the direction along afore mentioned rules equally spaced sets, in row adjacent one another are, and the recess of the row of certain row adjacency is between the recess and recess of certain row, and the center line of the recess of above-mentioned adjacency is positioned in the mode that the central authorities between two recesses of above-mentioned certain row pass through.In such " honeycomb structure shape ", can make two recesses that are formed on above-mentioned certain row significantly and be provided in gap turn narrow between the recess of the above-mentioned adjacency between this two recess, each recess is formed in the above-mentioned Printing Department thick and fast.
