Fig. 1 to 7 illustrates a preferred embodiment of the present invention.As shown in Fig. 1 to 5, the LCD panel comprises substrate 11.On whole base plate 11, form a plurality of sweep traces 12 with predetermined space.On whole base plate 11 lip-deep sweep traces 2, form insulation course 13.On insulation course 13 on whole base plate 11 surfaces, form a plurality of signal wires 14 with predetermined space, with sweep trace 12 perpendicular.The place, point of crossing forms a plurality of active components 15 between neighbor scanning line 12 and signal wire 14.As being indicated shown in " S " by dotted line among Fig. 1, on substrate, can see the display screen of area less than whole base plate.In this zone " S ", be formed with a plurality of pixel capacitors 16, corresponding to screen size S.In addition, on insulation course 13, form a plurality of sweep traces and connect liner 17.As Fig. 5 better shown in, liner extends to their final places that is electrically connected on insulation course and sweep trace 12, as hereinafter illustrated.In the zone outside the display screen " S " of required product, connect liner and be connected with sweep trace.Also provide a plurality of signal wires to connect liner 18.As shown in Figure 4, still in the zone outside the final products display screen " S " of substrate, it is overlapping and be electrically connected that these connect liners and signal wire 14.

As shown in Figure 4, signal wire connection liner 18 also directly contacts with signal wire 14 overlaids.This overlapping formation realizes that automatically signal wire connects being electrically connected between liner 18 and the signal line leads 14 '.Therefore, the signal of input signal cable connection liner 18 directly is sent to signal wire 14.

On the other hand, as shown in Figure 5, it is overlapping with sweep trace lead-in wire 12 ' that sweep trace connects liner 17, but between connection liner and sweep trace a layer insulating 13 is arranged, and stops directly to electrically contact.Therefore, external signal is not directly to be sent to sweep trace lead-in wire 12 ', because sweep trace connection liner 17 does not directly contact with sweep trace lead-in wire 12 ' in this formation.So,, laser beam is applied to sweep trace connects on liner 17 and the sweep trace lead-in wire 12 ' zone 100 of waiting to be electrically connected, so that the insulation course 13 on the burn 100 will connect welding with backing and receive on the sweep trace as shown in 6 and 7.As shown in Figure 7, this allows sweep trace connection liner 17 to be electrically connected with sweep trace lead-in wire 12 '.In Fig. 7, zone 19 is parts that part is electrically connected by applying laser beam.This makes the signal that is input to sweep trace connection liner 17 be sent to sweep trace 12.

As shown in Figure 1, sweep trace and signal line leads also appear at signal wire and are connected liner 8 and are connected outside the liner 7 with sweep trace.In manufacture method of the present invention, keep these lead-in wires.They are not that LCD operation institute is essential, yet, do not need to remove these lead-in wires yet.

Then, method according to manufacturing of the present invention LCD panel will be described below.

At first, on substrate, form sweep trace 12 and active matrix element 9.No matter the size of final products how, on the whole surface of substrate 11, form by the first metal sweep trace 12 with predetermined space.Then, utilize predetermined mask on sweep trace 12 and signal wire 14 position overlapped, to form active component 15.Active component 15 is bottom grid TFT (thin film transistor (TFT)) preferably.In this step, form insulation course 13 and semiconductor layer (not shown) as gate insulator.Then, on the whole surface of substrate, form again by the second metal signal wire 14 with predetermined space, with sweep trace 12 perpendicular.In these steps, active component 15, sweep trace 12 and signal wire 14 are to utilize for whole base plate surface speech same mask to form, and regardless of the yardstick of required final products how.

Then, utilize identical materials and for the patterned mask of the required screen size S of final products exploitation forms pixel electrode 16 simultaneously, sweep trace is connected liner 17 and is connected liner 18 with signal wire.In this case, in the zone outside the screen size S of final products, sweep trace connection liner 17 is connected liner 18 with signal wire overlapping with sweep trace lead-in wire 12 ' and signal line leads 14 ' respectively.In other words, shown in Fig. 2 and 3, each signal wire connects a part and each signal line leads 14 ' overlaid of liner 18, and each sweep trace connects a part and each sweep trace lead-in wire 12 ' overlaid of liner 17.Adopting laser beam to make sweep trace lead-in wire 12 ' be connected liner 17 with sweep trace then is electrically connected.

In transmission-type LCD panel, adopt transparent ITO (tin indium oxide) as pixel capacitors usually, in the reflection type LCD panel, adopt materials such as Al, Ag.

Then can become be suitable for the less substrate of each product size the substrate cut so made and be used for the LCD panel of required size is made product.

Utilize this manufacture method, on substrate, form sweep trace 12, active matrix element and signal wire 14, as long as pixel pitch is identical, no matter final products screen size S how with a kind of same size.So, in this fabrication phase, can adopt the patterned mask of same size.In other words, even the product size difference, the present invention can utilize a kind of shared mask to make the LCD panel, therefore, has reduced the number of making the required mask of different product.In addition, in common step, can prevent to change mask and the loss that causes.

In addition, owing to the LCD panel that test is had different size, only need make the mask of the different pattern step of required corresponding size, so the development time can be shortened.In addition, can finish the manufacturing step that forms active matrix element, sweep trace 12 and signal wire 14, before the size of determining the LCD panel, produce raw material in advance.This makes it possible to effectively utilize manufacturing equipment.Utilize the substrate of shared mask manufacturing can be considered to the shared semi-manufacture product of different screen sizes to a certain extent.Therefore, this semi-manufacture product be can sell, other department or other company for example are sold to.

In above-mentioned preferred embodiment, sweep trace 12 is insulated 13 covering of layer.Yet identical method also can be applied to adopt top gate TFT to be insulated layer 13 situation about being covered as active component and signal wire 14.

In above example embodiment, owing to apply the result of laser beam, only some is connected 18 electrical connections of liner 17 or signal wire connection liner with every sweep trace in every sweep trace 12 or the signal wire 14.The bonding pad can be amplified, as among Fig. 8 by shown in the zone 101, therefore can further increase the reliability of bonding pad.Bigger bonding pad causes the less heat in junction to produce, and flows through the bonding pad to allow higher current density.

Is connected with sweep trace respectively in the overlapping a part of zone of liner 17 or signal wire connection liner 18 in sweep trace lead-in wire 12 ' or signal line leads 14 ' and can form insulation course 13, as shown in Figure 9.This arrangement has been eliminated after forming sweep trace connection liner 17 or signal wire connection liner 18 needs to apply laser beam.

If adopt the method that does not form insulation course 13, so, it has the advantage that cancellation applies the laser beam step.If adopt by illuminating laser beam and realize the method that is electrically connected, so, it has the advantage that can not cause damage in afterwards the step, because all sweep trace 12 or the signal wires 14 of insulation course 13 protections.

Best, be scanned line and connect liner 17 or signal wire and connect the area that zone that liner 18 occupies almost is equivalent to a pixel capacitors 16.Yet, connecting adjacent scanning lines connection liner 17 on the scan-line direction or on the signal wire direction, connecting adjacent signals line connection liner 18, as Figure 11 and shown in Figure 10, can make this enlarged areas, so that realize safer electrical connection by respectively.

If utilize the conventional art plan to make a big panel, so,, just need abandon whole base plate even in the step that forms active matrix element, only have a defective.Yet, by adopting method of the present invention, on the processing line of producing a plurality of small panel, can defective substrate for example shown in Figure 12 A, be remedied, thereby the substrate portion beyond the defect area is utilized effectively.(for example see Figure 12 B, from bigger panel, can cut out a plurality of small panel here, thereby avoid defective element.If) plan only to produce a LCD panel from a substrate, so, can not accept flawless panel.Yet,, can from 16 panels, make 15 flawless panels 10, for example shown in 12A and 12B if plan produces a plurality of panels from a substrate.

In this example embodiment, first metal adopts second metal as signal wire 14 as sweep trace 12.Yet first and second metals can be the metals of same type.

In preferred embodiment, active component 5, sweep trace 12 and signal wire 14 utilize separately mask to form, and are common for the whole dimension of substrate, no matter the size of final products how.Then, pixel capacitors 16, sweep trace connect liner 17 is connected liner 18 with signal wire are to utilize same material and corresponding to the patterned mask formation of required screen size S.This makes it possible to form simultaneously pixel capacitors 16, sweep trace connects liner 17 and is connected liner 18 with signal wire, has therefore improved technological process efficient.Yet the present invention is not limited to this technological process.Active component 15 and sweep trace 12 can utilize the specific mask that whole base plate is had a kind of shared pattern to form.Therefore, signal wire 14, pixel capacitors 16, sweep trace connect liner 17 and are connected liner 18 with signal wire and can utilize the patterned mask (Figure 13 comparison diagram 4) corresponding to required screen size S to adopt same material formation.This further makes that removing pixel capacitors 16, sweep trace connects liner 17 and is connected with signal wire and forms signal lead 14 liner 18 simultaneously and become possibility, reduces manufacturing step and further raising technological process efficient.

Have, preferred embodiment has been described and has been formed sweep trace and connect liner 17 and is connected 18 while of liner active matrix element with signal wire and still remains on situation on the whole base plate again.Yet, can remove usually by etching and not produce a part of active matrix element of effect showing, can form after this and is connected liner 17 or signal wire connection liner 18 with the sweep trace that connects up.This makes to have higher dirigibility in the collimation of each connection liner.In this case, can form pixel capacitors 16 in advance, perhaps can form sweep trace simultaneously and connect liner 17 or signal wire connection liner 18 and pixel capacitors 16.Therefore, the present invention has no matter product size allows to use to a certain extent the effect of shared technological process.

As mentioned above, even make LCD panels new and different screen sizes, the present invention can shorten the cycle of development phase and reduce the number of times of mask conversion in the photograph technological process, because can the generation of new mask only be limited in the relevant mask of different screen sizes on, can adopt for the common mask of all screen sizes and make other element.
