Embodiment Construction

[0030] Embodiments of the present invention will be described below based on the drawings.

[0031] Such as figure 1 As shown, the substrate 1 for an organic EL device includes a light-transmitting plate 2 , a concavo-convex layer 3 , a high-refractive index layer 4 , and a transparent conductive layer 5 in the thickness direction in this order. The light-transmitting plate 2 , the concave-convex layer 3 , the high-refractive-index layer 4 and the transparent conductive layer 5 are respectively light-transmitting.

[0032] The light-transmitting plate 2 is formed of glass, resin, or the like. Examples of glass forming the light-transmitting plate 2 include soda lime glass, borosilicate glass, alkali-free glass, quartz glass, and the like. Examples of the resin forming the light-transmitting plate 2 include acrylic resin, silicone resin, epoxy resin, polyester fiber resin, polycarbonate resin, and the like.

[0033]The concavo-convex layer 3 is composed of a glass fired laye...

Abstract

Provided is an organic EL device substrate 1 provided with a transparent plate, a high refractive index layer 4, and a transparent conductive layer 5 in this order in the thickness direction, the organic EL device substrate 1 having a recessed groove portion 6 for dividing the transparent conductive layer 5 into at least a first region R1 and a second region R2, wherein, when the thickness of thetransparent conductive layer 5 is t1([mu]m), the minimum width of the recessed groove portion 6 is w1([mu]m), and the maximum depth of the recessed groove portion 6 from a surface 5a of the transparent conductive layer 5 is d1([mu]m), the surface 5a is on the opposite side of the high refractive index layer 4, and the relationship of t1<=d1 and d1 / {(w1)0.5}<0.1 is established.

Description

technical field [0001] The present invention relates to a substrate for an organic EL device, an organic EL device using the substrate, and a method for producing the same. Background technique [0002] In recent years, the use of organic EL devices using organic EL (electroluminescence) elements has attracted attention in various devices such as displays and lighting for the purpose of thinning and reducing power consumption. However, the luminance of organic EL elements is often insufficient especially when used as a light source for illumination, and it is true that further improvement in light extraction efficiency is required. [0003] Therefore, for example, Patent Document 1 discloses a substrate for an organic EL device having a function of scattering light from an organic EL element in order to improve light extraction efficiency. In detail, the substrate for an organic EL device disclosed in the document includes a glass plate on which a surface on which a transpa...
