224hatm.
The result of test is that permeability is minimum under 3 layers the situation, for the total (157.5) under the permeability situation of no gas barrier film, roughly be 20% (=32.45/157.5).Under 2 layers the situation, permeability is time low, for the situation of no gas barrier film, be roughly 32% (=50.19/157.5).In addition, under 1 layer the situation, transmitance is identical with 2 layers situation.
In addition, although do not illustrate in the drawings, covering 12 is compound substances of PMMA and polycarbonate, and gas barrier film 16 is 3 layers of structure, when adhesives 14 is the combination of propylene resin, because permeability is low, is desirable.
In addition, cover 12 is polycarbonate, and gas barrier film 16 is 2 layers of structure, and adhesives 14 is epoxies when being the combination of resin, and permeability is low, is desirable.
(manufacture method)
The manufacture method of the liquid crystal indicator 1 of Fig. 6 key diagram 1.
At first, respectively in the surface and the bottom surface of polarization plate 13, the adhesives 14 and 15 of applying sheet.The polarization plate 13 of adhesives 14 and 15 of having fitted is cut into the size of 1 liquid crystal indicator 1.
Then, on the surface of display panel 11, make the unit 100 that display panel 11 and polarization plate 13 are fitted, sealing adhesives 15.
On the other hand, cover the state that 12 former states keep big plate unchangeably, on a face of the cover 12 of this big plate, form gas barrier films 16 by evaporations such as coating or sputters.Then, cutting is provided with the big plate cover 12 of gas barrier film 16, makes being fitted in a unit 101 on the display panel 11.
2 unit 100 that make and 101, pressurizing attaching makes gas barrier film 16 be close to adhesives 14, finishes liquid crystal indicator shown in Figure 11.This applying also can be pressurizeed and be heated and carry out.
In addition, fitted in 2 unit 100 and 101, make gas barrier film 16 be close to adhesives 14, finish liquid crystal indicator 1.
Variation
Then, do an explanation with regard to variation.
In liquid crystal indicator, touch-screen is set sometimes.Fig. 7 to Fig. 9 represents to comprise the structure of the liquid crystal indicator of touch-screen.Liquid crystal indicator has under the situation of touch-screen, watches the side configuration cover as protective material at its touch-screen.Touch-screen for example is the electrostatic capacitive panel.
In liquid crystal indicator 1A shown in Figure 7, in Fig. 1 polarization plate 13 display panels 11 1 sides, touch-screen 17 is fitted on the polarization plate 13 through adhesives 15, and the space segment 18 with predetermined distance is set between touch-screen 17 and the display panel 11.
In liquid crystal indicator 1B shown in Figure 8, in Fig. 1 polarization plate 13 covers 12 1 sides, touch-screen 17 is fitted on the polarization plate 13, in addition through adhesives 14, cover 12 1 sides at touch-screen 17 are provided with adhesives 19, fit through adhesives 19 touch-screens 17 and cover 12.In this case, configuration gas barrier film 16 between cover 12 and the adhesives 19.
In liquid crystal indicator 1C shown in Figure 9, in Fig. 1 polarization plate 13 covers 12 1 sides, through space segment 20 touch-screen 17 is set, in addition with predetermined distance, cover 12 1 sides of touch-screen 17 are provided with adhesives 19, fit through adhesives 19 touch-screens 17 and cover 12.In this case, configuration gas barrier film 16 between cover 12 and the adhesives 19.
In each liquid crystal indicator of the Fig. 7 to Fig. 9 as above, gas barrier film 16 can both prevent that gas is from covering 12 discharges.
In addition, electro-optical device of the present invention can be applied to various liquid crystal indicators.In addition, display panels not only, the present invention can be used for the device various electro-optical devices such as (Field Emission Display, surface conduction electron emission display devices etc.) of el light emitting device, Organnic electroluminescent device, plasm display device, electrophoretic display apparatus, employing arresting element equally.
Then, just have the liquid crystal indicator relevant and do an explanation as the electronic equipment of display device with the foregoing description.Figure 10 is the skeleton view of expression as the outward appearance of the portable phone of electronic equipment.As shown in figure 10, portable phone 1200 with receiving mouth 1204, mouth piece 1206, also has the liquid crystal indicator 1 that is provided with as above-mentioned electro-optical device except that a plurality of action buttons 1202.
As the electronic equipment that can adopt according to electro-optical device of the present invention, portable data assistance), portable personal computer, digital camera, on-board screen, DITEC Digital Television Camera, LCD TV, find a view type or direct viewing type video tape recorder, auto-navigation system device, beeper, electronics miscellanies basis, desk-top computer, word processor workstation, television telephone set, POS terminating machine etc. except that portable phone, also has PDA (personal digital assistant:.
The invention is not restricted to the foregoing description, in the scope that does not change main points of the present invention, can carry out various changes and modification etc.
