Embodiment one, the uniform resistivity of resistance bolck 22, the density that is resistance bolck 22 diverse locations is identical, length direction along resistance bolck 22, resistance bolck 22 offers from the groove 23 of the end to end of resistance bolck 22 on the face of liquid crystal layer 30, the shape of cross section of groove 23 broad ways is arc, and groove 23 is with center line AA ' symmetry, in groove 23 bottom surfaces, parallel with center line AA ' each on straight line distance on to resistance bolck 22 towards the bottom surface of second substrate 20 of appointing equates, so that the two ends of the resistance of resistance bolck 22 from resistance bolck 22 Widths increase gradually to resistance bolck 22 region relative with center line AA '.
Particularly, please continue to refer to Fig. 2 and Fig. 3, resistance bolck 22 offers the groove 23 connecting with resistance bolck 22 two ends on the face of public electrode 11, the shape of cross section of groove 23 is arc, and the diverse location on the length direction of resistance bolck 22, perpendicular to the cross section of the length direction of resistance bolck 22, i.e. B as shown in Figure 3

1the shape of cross section of position and area of section, B
2-B
2the shape of cross section of position and area of section, B
n-B
nthe shape of cross section of position is identical with area of section, and groove 23 is to be parallel to the length bearing of trend of resistance bolck 22 and by the center line AA ' symmetry of resistance bolck 22 deciles; That is to say, along the length direction of resistance bolck 22, the degree of depth of groove 23 is changeless from the end to end of resistance bolck 22; But the Width along resistance bolck 22, the degree of depth of groove 23 increases to resistance bolck 22 region corresponding with center line AA ' gradually from being positioned at two edges of the resistance bolck 22 of center line AA ' both sides, from the thickness of resistance bolck 22 both sides of the edge, to resistance bolck 22 center, reduces gradually; Accordingly, the resistance of resistance bolck 22 increasing gradually to resistance bolck 22 and center line AA ' corresponding region from both sides of the edge.
Between resistance bolck 22 and conductive lead wire 25, position relationship is described in above-mentioned two embodiment, therefore, do not repeat them here, when driving circuit applies voltage by 25 pairs of resistance bolcks 22 of a conductive lead wire, the voltage now applying is positive voltage, because conductive lead wire 25 is positioned at the coupling part of resistance bolck 22 region that resistance bolck 22 is corresponding with center line AA ', and the two ends of the resistance of resistance bolck 22 from resistance bolck 22 Widths increase gradually to resistance bolck 22 region relative with described center line AA ', therefore, on resistance bolck 22, magnitude of voltage reduces to two ends gradually from resistance bolck 22 region relative with described center line AA ', along the Width of resistance bolck 22, from resistance bolck 22 region relative with described center line AA ' to two ends, resistance bolck 22 each locational voltages change by the voltage curve with certain rule, electric potential difference between corresponding resistance bolck 22 and public electrode 11 also changes with above-mentioned voltage curve, thereby make between resistance bolck 22 and public electrode 11 electric field that forms electric field intensity also with changing according to above-mentioned voltage curve, make each liquid crystal molecule in the liquid crystal layer 30 between resistance bolck 22 and public electrode 11 produce deflection in various degree, and then make liquid crystal layer 30 produce the function of lens.
