Organic layer 13 is made up of electron supplying layer, luminescent layer, electric hole transfer layer.In addition, negative electrode 12 is made up of with laminated body or calcium layer (Ca layer) that silver layer (Ag layer) is formed for example aluminium lamination (Al layer) or magnesium layer (Mg layer).At this, comparatively ideal is that the thickness of anode 11 is 100nm, and the thickness of negative electrode 12 is 500nm, and the thickness of organic layer 13 is 100nm.In addition, also can adopt the inorganic electroluminescence component layer to replace organic EL component layer 15.
In organic el element layer 15, the part of the organic layer 13 of double team about in the of 12 becomes light-emitting zone 13a by anode 11 and negative electrode.That is the organic layer 13 that is positioned under the negative electrode 12 is light-emitting zone 13a, and when observing to overlook, this light-emitting zone 13a also possesses the raster shape identical with negative electrode 12.Apply positive current potential by antianode 11, and anticathode 12 applies negative current potential, can make light-emitting zone 13a luminous.
The organic layer 13 in the zone beyond this is not luminous, and becomes non-luminous region.In addition, by covering the patterned negative electrode 12 of raster shape that is, form light shield layer 16.Light shield layer 16 and the negative electrode 12 same patterns that form raster shape.Light shield layer 16 is used for covering the light that radiates toward the top from light-emitting zone 13a, therefore as long as be the reflection layer that light can be reflected, or the light absorbing zone that light is absorbed is got final product.The thickness of light shield layer 16 is more satisfactory to be below the 10nm.
Reflection layer for example can be formed by aluminium lamination (Al layer).Light absorbing zone can be by the black pigment layer that comprises black pigment in photoresist, or comprising the black dyes layer of black dyes or chromium oxide layer in photoresist waits and form.
From the light of above-mentioned light-emitting zone 13a, by transparent anode 11 and the 1st transparency carrier 10, to reflection type LCD 300 irradiations towards the below.In addition, from the light of above-mentioned light-emitting zone 13a towards the top, by negative electrode 12 and light shield layer 16 and toward the below reflection or be absorbed, therefore, can prevent to come from the light of light-emitting zone 13a as far as possible, directly enter the top that is positioned at lighting device 200 and the sight line of the observer 113 who watches toward the below.
In the above-described configuration, negative electrode 12 is patterned as the shape of tool grating at regular intervals, though anode 11 does not carry out patterning, also negative electrode 12 and anode 11 can be exchanged.That is, in Fig. 1, anode 11 can be configured in the position of negative electrode 12, negative electrode 12 is configured in the position of anode 11.And making anode 11 patternings, 12 on negative electrode is not patterned.In addition, about anode 11 and negative electrode 12, also can be not patterned and comprehensive formation be the substitute is, also can be in the electron supplying layer that constitutes organic layer 13, luminescent layer, electric hole transfer layer at least one deck give patterning.That is the zone of these 3 layers of formation becomes light-emitting zone, and the zone that lacks in 3 layers arbitrary layer is a non-luminous region.
In addition, with regard to promoting shaded effect, more satisfactory is that the width of the more patterned negative electrode 12 (or anode) of the width of light shield layer 16 is greatly good.In addition, as shown in Figure 3, distance L 1 between the edge of patterned negative electrode 12 (or anode) and the edge of light shield layer 16, equate with the thickness sum L2 of the thickness of the light-emitting zone 13a of organic layer 13 and patterned negative electrode 12 (or anode) or bigger, can further promote shaded effect, thus comparatively desirable.
In addition, with regard to can not producing the difference sensation to observer 113 vision, comparatively ideal is that the spacing of the grating of patterned negative electrode 12 (or anode) (in Fig. 2, being the size of P1, P2) is below the 1mm.
Next the structure of the reflection type LCD 300 that throws light on above-mentioned lighting device 200 of explanation, with and and lighting device 200 between marriage relation.On each pixel on the TFT substrate of forming by glass substrate 30, form the thin film transistor (TFT) 31 (hereinafter referred to as TFT) that switches usefulness.TFT31 is covered by interlayer dielectric 32, on interlayer dielectric 32, forms corresponding to each TFT31 and by the pixel electrode of forming as the reflecting material of aluminium (Al) 33.Pixel electrode 33 passes through interlayer dielectric 32 formed contact hole CH, and is connected in drain or the source electrode of pairing TFT31.
The TFT substrate 30 that pixel electrode 33 forms relatively to, and dispose the subtend substrate of forming by glass substrate 34.On the surface of subtend substrate 34, form common electrode 35 by ITO formed.At the back side of subtend substrate 34, laminated in regular turn light scattering layer 36, the deflecting plate of being formed by the diffusion bonding layer 37.Light scattering layer 36 is used for making the light that comes from lighting device 200 to produce scattering, and is radiated at equably on the pixel electrode 33.Between this subtend substrate 34 and TFT substrate 30, enclose liquid crystal layer 40.
