The liquid crystal layer 30 is arranged at the side of the transparency conducting layer 20 away from the transparent flexible substrate 10 and right Should be in the display part 21, it is saturating away from this that the one patterned metal conducting layer 41 is arranged at the transparency conducting layer 20 The side of bright flexible substrate 10 and shape correspond to the one patterned circuit connecting section 23, and its material can be copper Deng conducting metal, the calculation process element 60 is electrically connected at the one patterned metal conducting layer 41, and the electricity Source delivery member 70 is then electrically connected with the one patterned metal conducting layer 41 to provide required electric power.Thereby, The transparency conducting layer 20 is directly formed in being led in the transparent flexible substrate 10 with directly forming the one patterned metal Electric layer 41 is on the transparency conducting layer 20, when can not produce contact, and then prevent terminating in bending, the figure The problem of sample metal conducting layer 41 or the transparency conducting layer 20 are broken and make element not use.

In the present embodiment, the liquid crystal layer 30 has multiple liquid crystal 31, and those liquid crystal 31 respectively have one White displays portion 311 of black display portion 312 and one, and when actual assembled, more can be in the liquid crystal layer 30 An electrode layer (not shown) is set away from the transparent flexible substrate 10, uses and is produced with the transparency conducting layer 20 Corresponding electric field, those liquid crystal 31 are made to be overturn in correspondence position, when operated, power supply supply Part 70 provides the electric power, is operated the calculation process element 60, and then transmits a signal, and this is transparent Conductive layer 20 produces corresponding electric field after receiving the signal with the electrode layer, and then makes those liquid crystal 31 Overturn in correspondence position, and the numeral for corresponding to the signal or symbol etc. can be showed.

Continuous collocation is refering to shown in Fig. 3 and Fig. 4 A to Fig. 4 D, being the Making programme of the present embodiment, in this wherein, The material of each element at this as it was previously stated, do not repeat separately then.The making step of the present embodiment is as follows:

S1:As shown in Figure 4 A and 4 B shown in FIG., a transparency conducting layer 20 is formed in a transparent flexible substrate 10 On, a metal conducting layer 40 is then re-formed on the transparency conducting layer 20, the transparency conducting layer 20 include a display part 21 and one adjacent to the display part 21 circuit connecting section 22, need to especially say Bright, the metal conducting layer 40 can be copper, and the transparency conducting layer 20 is tin indium oxide, and in this implementation It is that directly copper is formed on tin indium oxide in example, that is, and without the setting of any padded coaming, Directly the metal conducting layer 40 is formed on the transparency conducting layer 20.

S2:As shown in Figure 4 C, the metal conducting layer 40 being first pointed on the display part 21 is etched Expose the display part 21, then, then to the circuit connecting section 22 and positioned at the circuit connecting section 22 On the metal conducting layer 40 be etched, the circuit connecting section 22 is distinguished with the metal conducting layer 40 An one patterned circuit connecting section 23 and an one patterned metal conducting layer 41 are formed, and the one patterned circuit connects Socket part 23 is corresponding with the shape of the one patterned metal conducting layer 41, through the one patterned metal conducting layer 41 increase circuits extend to electric conductivity when outside display part 21, avoid the material because circuit connecting section 22 Matter for electrically conducting transparent material influence electrical conductivity resistance value it is excessive the problem of.

S3:As shown in Figure 4 D, a liquid crystal layer 30 is formed on the display part 21, and the liquid crystal layer 30 has Multiple liquid crystal 31, and those liquid crystal 31 respectively have a black display portion 312 and a white displays portion 311, And a calculation process element 60 and a power supply delivery member 70 (being shown in Figure 1A) are electrically connected at the one patterned Metal conducting layer 41.

Continuous collocation, for the Application Example of the present invention, is connected in above-mentioned steps refering to shown in Fig. 5 and Fig. 6 After S3, following steps have been further included:

S4:A guard member 91 is formed in the side of the transparent flexible substrate 10 away from the transparency conducting layer 20, And a display window 93 of the guard member 91 is set to correspond to the display part 21.And during actual assembled, also may be used Additionally to set another guard member (not shown) in the position of the relative guard member 91, will the present invention set It is placed between the guard member 91 and another guard member, and can further protects the present invention.

In addition, as shown in fig. 6, the guard member 91 can more include one to house the transparent flexible base The groove 92 of plate 10, thus, it is possible to reduce the thickness of this application embodiment.

And if the liquid crystal layer 30 is arranged at away from should be in order to protect the part of the side of the transparent flexible substrate 10 Also to be transparent, the display window 93 can also be arranged in another guard member and correspond to the display part 21, present invention could apply to the fields such as Electronic Paper, credit card.Specifically, applied to credit On card and when when being swiped the card on network, the liquid crystal layer 30 can show a sets of numbers, except general defeated Enter outside password, holder must input the number on relevant apparatus, and can just swipe the card success, improve brush The security of card.

In summary, due to the invention has the characteristics that:

First, by the transparency conducting layer and the one patterned metal conducting layer is directly formed, avoid in display member Electrical contact is produced between part and flexible circuit board and then anti-when terminating in bending, the one patterned metal conducting layer or The electrically conducting transparent fault rupture and the problem of element is not used, and can be applied to the neck such as Electronic Paper, credit card Domain.

2nd, by the setting of the guard member, the present invention can be further protected, such as prevents aqueous vapor from corroding Etc., improve and use the upper life-span.

3rd, by the setting of the groove, the transparent flexible substrate can be accommodated, to reduce thickness.
