<third embodiment>
Next, being described in detail referring to third embodiment of the attached drawing to the utility model.For implementing with first
The duplicate content of mode, omits the description.Fig. 4 is the vertical view signal for indicating the light-emitting surface of the organic EL panel 10 in present embodiment
Figure, (a) of Fig. 4 show the example that organic luminous layer 12 is divided into three parts, and (b) of Fig. 4 is shown organic luminous layer
12 are divided into tetrameric example.
In (a) of Fig. 4, the organic luminous layer 12 on substrate 11 is divided into middle section 12a and periphery area in face
Domain 12d.In addition, the current density for flowing to middle section 12a is set to be greater than peripheral edge margin 12d.
In (b) of Fig. 4, the organic luminous layer 12 on substrate 11 is divided into the middle section 12a in face, in encirclement
The intermediate region 12b that entreats the mode in the outside of region 12a to be formed, it is formed in a manner of the outside for surrounding intermediate region 12b
Between the region 12c and peripheral edge margin 12d formed in a manner of surrounding most peripheral.In addition, according to middle section 12a, intermediate region
The size of the sequence setting electric current density of 12b, intermediate region 12c, peripheral edge margin 12d.
In organic EL panel 10, there is following problem: if moisture enters inside from the most peripheral of organic luminous layer 12, having
The deterioration of machine luminescent layer 12 develops and generates blackspot, and non-luminous non-luminous region flowing through electric current is caused to increase.In addition,
The development of deterioration in organic luminous layer 12 and the generation of blackspot have the following characteristics that the current density flowed through is bigger, easier production
It is raw.
In the present embodiment, in the peripheral edge margin 12d of organic luminous layer 12, compared to middle section 12a, make to flow through
Current density is smaller, therefore is being easy to reduce current density near the periphery because of the generations deterioration such as entrance of moisture, is able to suppress
The development of deterioration.Thereby, it is possible to reduce the reply component for preventing organic EL panel from deteriorating, number of components can be reduced.
In addition, there are illusion thinking that middle section is nearby compared in the periphery for carrying out luminous region in the vision of the mankind
Brighter edge effect.In peripheral edge margin 12d, since the edge effect can be utilized, even if making in current density ratio
It entreats region 12a small, also can see the brightness of same degree in middle section 12a and peripheral edge margin 12d.It can get edge effect
Range be 1~2mm or so, therefore the width of peripheral edge margin 12d is preferably the range of 1~2mm or so.
In addition, intermediate region 12b, the 12c of (b) of Fig. 4 are configured at the peripheral edge margin 12d and middle section 12a of most peripheral
Between, set on the range that can not obtain edge effect.In this case, by making current density middle section 12a, middle area
The size of the sequence of domain 12b, intermediate region 12c, can be to have the brightness of gradient from middle section 12a to peripheral edge margin 12d
Distribution, which obtains, has relief sending light.
Fig. 5 is the wiring for indicating the transparent electrode 13 for realizing the light-emitting surface of organic EL panel 10 shown in Fig. 4 (b)
The schematic top plan view of pattern.As shown in figure 5, the transparent electrode 13 of organic EL panel 10 with middle section shown in (b) of Fig. 4
12a, intermediate region 12b, 12c, the corresponding mode of peripheral edge margin 12d are respectively formed with central wiring portion 13a, intermediate wiring portion
13b, 13c, periphery wiring portion 13d.
Therefore, the current density ratio that organic luminous layer 12 is flowed to from periphery wiring portion 13d has from central wiring portion 13a flow direction
The current density of machine luminescent layer 12 is small.In addition, from intermediate wiring portion 13b, 13c flow to the current density ratio of organic luminous layer 12 from
The current density that central wiring portion 13a flows to organic luminous layer 12 is small, and than flowing to organic luminous layer 12 from periphery wiring portion 13d
Current density it is big.
In addition, being formed locally as shown in partial enlarged view in figure in intermediate wiring portion 13b, 13c, periphery wiring portion 13d
There is joint-cutting.Extend positioned at the central wiring portion 13a of inside, a part of intermediate wiring portion 13b, 13c as wiring pattern, leads to
Cross the end that the joint-cutting part leads to substrate 11.In the end of substrate 11, as shown in Figure 1, transparent electrode 13 is electrically connected to confession
Electrical wiring 14.
Fig. 6 is the process chart for illustrating schematically that the manufacturing method of organic EL panel 10 shown in Fig. 4 (a).On a left side of Fig. 6
Side shows schematic top plan view, and lateral diagrammatic cross-section is shown on right side.
Firstly, as shown in (a) of Fig. 6, prepared substrate 11 forms the central wiring portion of transparent electrode 13 on the substrate 11
13a, periphery wiring portion 13d and for electrical wiring 14, use common photoetching technique to form pattern.Next, such as (b) institute of Fig. 6
