Description

Display device

Technical field

The utility model relates to display device.

Background technology

The wiring of the image element circuit of display floater extends on the glass substrate of display floater and the display floater peripheral part, has terminal.This terminal is electrically connected to the corresponding terminal that extends setting from drive IC by using bonding agent to carry out crimping, and described drive IC is formed on flexible film substrate (flexible cable (cable)), is used for driving image element circuit.And the display floater that this is connected and flexible film substrate consist of a display device.

But, in display device, there is following problem: in the situation that be formed with the glass substrate of terminal and be formed with adhesive-applying between the flexible film substrate of corresponding terminal and carry out crimping, bonding agent can flow out to the outside of flexible film substrate, easily produces bubble in the zone that bonding agent flows out.

This point discloses the structure of display device shown in Figure 11 in patent documentation 1.In this structure, be formed with the inoperative dummy electrode 104 of the driving of display floater on the glass substrate 101 in the outside of the extraction electrode 105 of flexible cable 102 and

glass substrate

101 and 106.

Like this, only in glass substrate 101 sides, dummy electrode 104 is set, and makes the height of its aspect ratio extraction electrode 105 high, make thus anisotropic conductive adhesive 103 not to flexible cable 102 outsides outflows.

The utility model content

The problem that utility model will solve

Yet, in the disclosed prior art of patent documentation 1, can produce following problem.

That is, along with the high-precision refinement of display floater, the wiring quantity that is arranged on flexible cable 102 increases, and the quantity of extraction electrode 106 also increases thereupon.In addition, in the situation that display floater is organic EL panel, drive with a large amount of electric currents, therefore be provided with the large power line of live width on flexible cable 102.

Thus, the wiring of flexible cable 102 is equipped on flexible cable 102 to high-density.Its result, the end of flexible cable 102 shortens with the distance that is equipped on outermost wiring, wiring need to be set near the end of flexible cable 102.

Content below having disclosed in patent documentation 1.That is, flexible cable 102 and glass substrate 101 are being carried out flexible cable 102 is pressed into glass substrate 101 when bonding.In this case, as shown in figure 12, the height of dummy electrode 104 that is arranged at glass substrate 101 sides is higher, and therefore, anisotropic conductive adhesive 103 can flow out from flexible cable 102 lateral flex cable 102 outsides.This anisotropic conductive adhesive 103 that flows out can hang down from flexible cable 102 side direction glass substrates 101 and flow, and thus, the anisotropic conductive adhesive 103 that spills can become block and solidify in the crimping process.Thus, just can't apply uniform power to flexible cable 102.

Its result, as shown in figure 13, the central portion with flexual flexible cable 102 can cave in, the whole warpage in the outside of flexible cable 102 and being out of shape.That is, block is understood the end of the flexible cable 102 of ejection and is made flexible cable 102 distortion.

Particularly, in the situation that wiring is set near the end of flexible cable 102, more strong to the ejection effect meeting of the end of flexible cable 102 by block.Thereby due to the ejection effect of this block to the end of flexible cable 102, the extraction electrode 105 of glass substrate 101 sides can't be electrically connected to the extraction electrode 106 of flexible cable 102 sides, so cause bad connection.Particularly, in the zone approaching with the zone that is formed with block, anisotropic conductive adhesive 103 easily produces bad connection.

20 and 60, outermost substrate wiring 21 outsides in multiple row substrate wiring 21 have dummy substrate wiring 22, and glass substrate 12 has the illusory panel wiring 14 with dummy substrate wiring 22 subtends.In addition, the height of dummy substrate wiring 22 is higher than the height of illusory panel wiring 14.

Below, the manufacture method of detailed description display device.

Flexible film substrate

20 and 60 is pressed into glass substrate 12 through same operation, and then by 40 pairs of bonding agent 30a heating of pressing member, bonding agent 30a is solidified, thus

flexible film substrate

20 and 60 and glass substrate 12 bonding, therefore, the below only illustrates the situation of flexible film substrate 20.

At first, as shown in Fig. 3 (a), prepare glass substrate 12, this glass substrate 12 is provided with panel wiring 13 and illusory panel wiring 14 in the zone of connecting up, and is provided with display pixel in the viewing area.Afterwards, on the wiring zone of glass substrate 12, that is to say on the periphery of glass substrate 12 and form bonding agent 30a with cover plate wiring 13 and illusory panel wiring 14.

Then, as shown in Fig. 3 (b), with and the mode of the wiring of glass substrate 12 zone subtend and make the mode of bonding agent 30a between flexible film substrate 20 and glass substrate 12, on each limit of glass substrate 12, polylith flexible film substrate 20 is set respectively.At this moment, polylith flexible film substrate 20 is arranged to substrate wiring 21 and dummy substrate wiring 22 and corresponding panel and is connected up 13 and illusory panel 14 subtends that connect up.

Then, shown in Fig. 3 (c), pressing member 40 by the back side that arrives to polylith flexible film substrate 20 (not forming the face of substrate wiring 21 and dummy substrate wiring 22), is pressed polylith flexible film substrate 20 simultaneously to glass substrate 12.Thus, conductive particle 31 during the state configuration that contacts with both between 13 to connect up at substrate wiring 21 and panel is included in bonding agent 30a, substrate wiring 21 is electrically connected to panel wiring 13, in addition, the state configuration conductive particle 31 to connect up and to contact with both between 14 at dummy substrate wiring 22 and illusory panel.Though not shown, still also can be used in the protection thin slice of protection flexible film substrate 20 between pressing member 40 and flexible film substrate 20.

At this moment, bonding agent 30a is because pressing member 40 presses, and through the gap of dummy substrate wiring 22 with illusory panel wiring 14, is subjected to dummy substrate wiring 22 guiding and flows out to glass substrate 12 surfaces.Thereby bonding agent 30a can not flow out to the surface of

flexible film substrate

20 and 60.

In addition, can by dummy substrate connect up 22 and illusory panel wiring 14 adjust the discharge of bonding agent 30a.At this, can suppress following situation: the outflow quantitative change of bonding agent 30a is many, the bonding agent 30a blocking that flows out and swelling can't be pressed into glass substrate 12 with

flexible film substrate

20 and 60 with uniform power, and substrate wiring 21 becomes unstable with the conducting that panel connects up between 13.Simultaneously, can also suppress to become unstable because of few both conducting of the quantitative change of the bonding agent 30a between 13 of connecting up of substrate wiring 21 and panel.

Then, as shown in Fig. 3 (d), by the heating of pressing member 40, heat and bonding agent 30a is heated from the back side of polylith flexible film substrate 20, make bonding agent 30a be solidified to form adhesive linkage 30.Thus, complete display device as shown in Fig. 3 (e).

As mentioned above, according to the display device of present embodiment, make during flexible film substrate 20 is crimped onto the operation of glass substrate 12, can by dummy substrate connect up 22 and illusory panel wiring 14 control outflow position and the discharge of bonding agent 30a.Its result can make substrate wiring 21 good with being electrically connected to of panel wiring 13.
