(3), printing envelope frame glue step, print the envelope frame glue of reservation shape at said flexible upper substrate or flexible infrabasal plate, and reserve and irritate brilliant mouthful;
(4), cladding plate and curing schedule, a side that flexible upper substrate and flexible infrabasal plate is had transparency electrode is relative, and said flexible upper substrate is covered on the said flexible infrabasal plate; Material according to envelope frame glue and micelle is different, adopts the method for hot pressing or UV irradiation, and said flexible upper substrate and flexible infrabasal plate are fixed together through micelle and envelope frame glue, constitutes liquid crystal cell;
(5), irritate brilliant for brilliant mouthful, from said filling and the filling that will fill the liquid crystal cell of liquid crystal material seal for brilliant mouthful.
If between said flexible upper substrate and flexible infrabasal plate, be provided with a plurality of identical shaped envelope frame glue unit; Can also before above-mentioned (5) step, be provided with the drawing step, promptly; Utilize and the consistent mould of envelope frame glue shape, strike out single liquid crystal cell along envelope frame glue outer edge.
After said (5) step, can also be provided with polaroid and paste step, there are the upper surface and the lower surface of the liquid crystal cell of liquid crystal to paste polaroid and following polaroid respectively in filling.
In the said method, the material of said micelle can be identical with the material of envelope frame glue.
In order to realize second purpose of the present invention; The present invention also provides a kind of flexible base, board LCD; Comprise flexible upper substrate and flexible infrabasal plate, on the said flexible upper substrate side relative with flexible infrabasal plate, be respectively equipped with transparency electrode and following transparency electrode, said flexible upper substrate is fixedly connected through envelope frame glue with flexible infrabasal plate; Be respectively equipped with alignment films and following alignment films on transparency electrode and the following transparency electrode on said; Be provided with spherical chock insulator matter and liquid crystal material between alignment films and the following alignment films on said, on said spherical chock insulator matter outer wall, be provided with colloid, said colloid links together said flexible upper substrate and flexible infrabasal plate.
Among the above-mentioned LCD, the material of said colloid can be identical with the material of envelope frame glue.
The present invention is printed on spherical chock insulator matter on the flexible base, board surface together with micelle owing to having adopted, and when cladding plate, together with envelope frame glue upper and lower flexible base, board is fixed together; Like this; Spherical chock insulator matter also advances to be positioned in the micelle together, and is connected firmly between the upper and lower flexible base, board, has both made at liquid crystal and has spread rapidly; Can not occur the problem that quilt is got excited because spherical chock insulator matter adhesion is not enough yet, solve the problem of the box thickness ununiformity of LCD display.
