This process is, first on array base palte or color membrane substrates, place mask plate as shown in Figure 5, then on this mask plate, be coated with the nonmetallic materials with light-proofness energy, thereby make sealed plastic box backing material can form the sealed plastic box substrate identical with the mask plate shape shown in Fig. 5, now again this mask plate is removed from array base palte or color membrane substrates, can on array base palte or color membrane substrates, form sealed plastic box substrate.With respect to aforementioned techniques scheme, this process has the effect of the realization of being simply easy to.
On the gluing region of array base palte 1, be provided for making the sealed plastic box substrate of the flattening surface that is coated with sealed plastic box figure, make the light signal that sensor receives can be because the unevenness of substrate surface produces deviation.After sealed plastic box has been coated with, can liquid crystal layer be set being coated with on the array base palte of sealed plastic box or color membrane substrates.This method that liquid crystal layer is set can, for any means of existing injection liquid crystal, repeat no more.
Finally, the array base palte of completing steps 101 and step 102 and color membrane substrates, to box, can be completed to the manufacture of panel of LCD.
Panel of LCD manufacture method of the present invention, expose and development treatment to laying sealed plastic box backing material on substrate by the mask plate matching with sealed plastic box shape, can obtain the sealed plastic box substrate matching with the shape of sealed plastic box figure, this sealed plastic box substrate can be optimized the uneven state on array base palte or color membrane substrates surface, makes the flattening surface in the gluing region that is coated with sealed plastic box.Therefore, in the time carrying out coating technique, the light signal that sensor receives can not produce deviation, thereby has improved the stability of coating technique, has reduced the control difficulty of coating technique, further improves product yield and production capacity.
Finally it should be noted that: above embodiment is only in order to technical scheme of the present invention to be described but not be limited, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can be modified or be equal to replacement technical scheme of the present invention, and these modifications or be equal to replacement and also can not make amended technical scheme depart from the spirit and scope of technical solution of the present invention.
