Fig. 4 is that synoptic diagram is looked on the right side of Fig. 1.
Fig. 5 is that the master of the photo-shield strip 5 among Fig. 3 looks synoptic diagram.
[embodiment]
Fig. 3, Fig. 4 and Fig. 5 show a kind of embodiment of the present utility model.Photo-shield strip 5 is selected for use black to step and is drawn adhesive tape (UV TAPE).
As shown in Figure 3 and Figure 4, this LCDs comprises first transparency carrier 2, the one side of first transparency carrier 2 is pasted with second transparency carrier 1 and nation has drive IC module 3 and flexible printed circuit board 4 surely, and another side is pasted with the photo-shield strip 5 that can block drive IC module 3; Photo-shield strip 5 extends outside the profile of first transparency carrier 2, and it is bonding with flexible printed circuit board 4 that photo-shield strip 5 exceeds the part of profile of first transparency carrier 2.
As shown in Figure 3, photo-shield strip 5 be shaped as the T font, the horizontal component of this T font is attached on first transparency carrier 2, the lower end of the vertical part of this T font is bonded on the flexible printed circuit board 4.Again, horizontal range between the right hand edge of the horizontal range between the left hand edge of the vertical distance between the coboundary of T font horizontal component and second transparency carrier, 1 lower limb 9, the left hand edge of T font horizontal component and first transparency carrier 2, the right hand edge of T font horizontal component and first transparency carrier 2 is 0.3～0.5mm, and the lower limb of T font horizontal component flushes with the lower limb of first transparency carrier 2; Horizontal range between the right hand edge of the horizontal range between the left hand edge of the vertical part of T font and the left hand edge of flexible printed circuit board 4, the right hand edge of the vertical part of T font and flexible printed circuit board 4 is 0.3～0.5mm.
