Abstract
A transparent electrode (11) the number of which corresponds to that of a picture element is formed on a liquid crystal display region on an inner surface of a liquid crystal panel substrate (10), and external connecting terminals (12) at free end portions of a plurality of leader lines (18) conductively connected to this transparent electrode on the outer side of the liquid crystal display region. On the inner surface of the liquid crystal panel substrate on which the transparent electrode, leader lines and external connecting terminals are formed, an acrylic thermosetting resin is applied to the whole area thereof to a small thickness by a spin-coating method to form a transparent insulating film (16). A polyimide resin is then applied to the portion of the liquid crystal display region which is on an outer surface of this transparent insulating film, and the resultant layer of polyimide resin is fired to form an orientation film (14). When this orientation film is rubbed by a rubbing roller, rubbing unevenness rarely occurs since the leader lines and external connecting terminals are covered with the transparent insulating film, so that the display unevenness on a liquid display panel decreases.

In the present embodiment, the part in the liquid crystal display district on the inner face of liquid crystal display substrate 10 forms transparency electrode 11 at each pixel region.And, owing to adhere to aluminium, adhere to other metal material, conduct electricity a plurality of extension lines 18 that are connected transparency electrode 11 so resemble to form from introversive its outside elongation in liquid crystal display district.Further, form the external connection terminals 12 that conduction is connected the most advanced and sophisticated unit of this extension line 18 in the outside in liquid crystal display district.The thickness of external connection terminals 12 is about 1000~2000 usually.
On the inner face of the liquid crystal display substrate 10 that forms this transparency electrode 11, extension line 18 and external connection terminals 12, apply the acrylic acid series thermoset resin by the spin coating thinly at whole face, make it sclerosis by the heating condition that is suitable for resin material, be processed into thickness at last and be about 100~200 , form transparent insulating film 16.Then, the coating polyimide resin is fired in the lip-deep liquid crystal display district of this transparent insulating film 16, forms the oriented film 14 of thickness 700~800 .
On the one hand, the liquid crystal display district on the inner face of liquid crystal display substrate 20 forms transparency electrode 21, printed and formed in its surface color filter 22.On the other hand, on whole of the outside that reaches the liquid crystal display district on the surface that comprises color filter 22, utilize the spin coating, form transparent insulating film 23 with above-mentioned transparent insulating film 16 identical materials with about 200 thickness.In the lip-deep liquid crystal display district of this transparent insulating film 23, usefulness and above-mentioned oriented film 14 identical materials form the oriented film 24 that almost has same thickness.
As above, on inner face, in the liquid crystal display substrate 10 and 20 of cambium layer structure, carry out Fig. 2 and Fig. 3 (state that expression is handled liquid crystal display substrate 10 among the figure.) shown in milled processed.The method of this milled processed has multiple.In the present embodiment, use and the surface to be had the grinding that the abrasive sheet of a lot of maos of 15a is wound on the columniform roller roll 15.And, with authorised pressure liquid crystal display substrate 10 cramp lappings are being rolled under 15 the state, with the surface in contact limit of liquid crystal display substrate to roll 15 the rotating sense of rotation rotation of moving direction equidirectional with grinding, the inner face of liquid crystal display substrate 10 is ground on the limit, the limit make grind roll mobile.
Thickness to external connection terminals 12 and extension line 18 forms above-mentioned transparent insulating film 16 as thin as a wafer, cover, so that the concavo-convex and outstanding shape that exists on the surface of externally splicing ear 12 and extension line 18 is relaxed, and because the formation of transparent insulating film 16 usefulness acrylic resins, so mantle friction is also lower than extension line 18 and external connection terminals 12.Thereby, roll 15 when grinding by grinding, between hair 15a and external connection terminals 12 and extension line 18, produce the smear metal of hair 15a, the situation that sidewall by external connection terminals 12 and extension line 18 removes does not take place in the part that only contacts external connection terminals 12 and extension line 18 by the bits with the bits that contact the oriented film material that produces of the oriented film of previous stage and hair 15a itself, and its result can be to the even milled processed of 14 executions of the oriented film in the liquid crystal display district.
To liquid crystal display substrate 20, liquid crystal display substrate 10 is same to implement above-mentioned milled processed with the orthogonal direction of milled processed direction that can carry out.Even at this liquid crystal display substrate 20, also be provided with a plurality of extension lines that conduction is connected a plurality of each transparency electrode 21, these extension line conductions are connected the said external splicing ear 12 that forms on the liquid crystal display substrate 10.
Then, as shown in Figure 1, under the state of the inner face that forms oriented film, by the encapsulant 30 bonding liquid crystal display substrate 10 and the liquid crystal display substrates 20 of formations such as ultraviolet hardening resin.Sealing material 30 forms frame-like so that impale the liquid crystal display district, constitutes the sealing liquid crystal district by bonding liquid crystal display substrate 10 and 20.Pictograph becomes seal such, makes the sealing liquid crystal district lack a part of encapsulant 30 in advance.
At last, inject liquid crystal 31,, form the LCDs of clamping liquid crystal layer like this seal sealing from seal., cut off remove a part of liquid crystal display substrate, expose the external connection terminals unit, remove transparent insulating film 16 on the covering surfaces by plasma polishing etc. thereafter.When a plurality of liquid crystal displays are formed integral body, cut off and isolate each liquid crystal display.
In above-mentioned example, only liquid crystal display substrate 10 forms external connection terminals unit 13, even but do not have the liquid crystal display substrate 20 of external connection terminals unit, because there is extension line in outer edge part in the liquid crystal display district, so can prevent from also to result from that the grinding of extension line is irregular.
, can not establish the external connection terminals unit here, in liquid crystal display substrate 20 square one-tenth external connection terminals unit at liquid crystal display substrate 10 yet.And, also can all establish the external connection terminals unit at two substrates 10,20.At this moment, though to liquid crystal display substrate 10,20 one of them, also form transparent insulating film 16,23, thus when even a substrate therein forms the external connection terminals unit, also can be identical with above-mentioned situation, prevent foot irregular to the milled processed of film.
If transparent insulating film the 16, the 23rd also can reduce the dielectric film of mantle friction than outside terminal unit 13, then be not limited to above-mentioned material, other materials also can.And, when making the liquid crystal display that constitutes the reflective liquid crystal display body, also can form opaque dielectric film at the substrate (particularly replacing transparency electrode to form the substrate of reflecting electrode) of reflection side.
In above-mentioned material, for guaranteeing the adhesiveness of liquid crystal display substrate and encapsulant, the thickness of transparent insulating film is preferably below 200 , and the thickness as being formed easily by spin coating etc. is preferably more than 100 .If transparent insulating film is also thicker than 200 , then adhesiveness descends, and in this liquid crystal display, the possibility of peeling off that probably takes place between substrate is big.
In general, at the low film place of mantle friction, adhesiveness is low, so even when replacing above-mentioned transparent insulating film to use the film of different materials, it is also meaningful to preventing peeling off of liquid crystal display substrate that the thickness attenuation is improved its adhesiveness.In the present invention, because the special low film of mantle friction that forms, so promptly use the also thin many films of thickness than external connection terminals, prevent aspect milled processed irregular also effective, on the other hand, in the outside terminal unit that constitutes concaveconvex shape, can improve covering the adhesiveness of the liquid crystal display substrate of the film that forms itself thinly.As formed film thickness, be preferably below 5~50% of outside terminal element thickness.
In the manufacturing process of prior liquid crystal display, the irregular irregular to a certain degree generation ratio that shows that causes of above-mentioned milled processed almost surpasses 90%, different therewith, utilize above-mentioned present embodiment, form in the liquid crystal display substrate of making dielectric film in the scope of about 150~190 of thickness, result from milled processed, irregular the falling sharply of observable demonstration be below 10%.Therefore, increase substantially the yield rate in the manufacturing process, improved the display quality of final finished greatly.
Have, in the above-described embodiments, at the whole inner face coating formation transparent insulation of liquid crystal display substrate, but for to obtain same effect, the unit on every side that is preferably in the liquid crystal display district that comprises extension line and outside terminal unit at least forms dielectric film again.Even at this moment and since by dielectric film evenly cover oriented film around, so can prevent the irregular of milled processed equally.
Fig. 4 represents the edge face structure with the LCDs of above-mentioned different embodiment.In this embodiment, be marked with same symbol in the part identical with the embodiment of front, it illustrates omission.In the present embodiment, it is identical with the embodiment of front at the tip portion of the extension line 18 that connects with transparency electrode 11 external connection terminals 12 these points to be set, but only form dielectric film 16 on liquid crystal display district and the extension line 18, externally not form this point of dielectric film on the splicing ear 12 different.
In the present embodiment, has this advantage: by the peripheral part 16a of configuration dielectric film on extension line 18, the grinding that can not prevent of external connection terminals 12 is irregular for resulting from, can prevent that in that to result from the grinding of the extension line 18 that forms than external connection terminals 12 part near apart from the liquid crystal display district irregular, the back need not removed the dielectric film on the external connection terminals 12 again.
Like this,, comprise extension line or the external connection terminals unit on every side in the liquid crystal display district of the part of one at least, can bring into play effect of the present invention by covering according to above-mentioned dielectric film.For example, as shown in Figure 4, only formation and above-mentioned transparent insulating film 16,23 same dielectric films get final product on extension line 18.Perhaps, for example the liquid crystal display district around in the unit, also can be only roll the external connection terminals 12 or the extension line 18 usefulness dielectric films of a side (upside in the liquid crystal display district among Fig. 2) of 15 milled processed and cover carrying out grinding shown in Figure 2 at first.The extension line 18 and the external connection terminals 12 that form at the downside in liquid crystal display district shown in Figure 2, the milled processed of grinding being rolled 15 liquid crystal display district is unaffected.
Utilizability on the industry
According to the present invention described above, because insulating barrier drawing unit around the liquid crystal display district The part of outlet and external connection terminals unit covers, and reduces mantle friction, so can reduce by connecing Touch the irregular of milled processed that lead-out wire and external connection terminals unit produce, can reduce liquid crystal display The demonstration of screen is irregular. Thereby, both improved the display quality of LCDs, can improve liquid crystal again Yield rate when display screen is made.
