Organic electroluminescence device including multi-layered protective layer

#The present application is based on, and claims priority from JP Application Serial Number 2020-000474, filed Jan. 6, 2020, the disclosure of which is hereby incorporated by reference herein in its entirety.

#The present disclosure relates to an organic electroluminescence device and an electronic apparatus.

#Organic electroluminescence (EL) devices including organic EL elements are known. The organic EL device is used as, for example, an organic EL display configured to display an image.

#FIG. 1 is a plan view illustrating an organic EL device according to a first exemplary embodiment.

#FIG. 2 is an equivalent circuit diagram of a sub-pixel illustrated in FIG. 1.

#FIG. 3 is a view illustrating a cross section taken along a line A-A illustrated in FIG. 1.

#Preferred exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. Note that, in the drawings, dimensions and scales of sections are differed from actual dimensions and scales as appropriate, and some of the sections are schematically illustrated to make them easily recognizable. Further, the scope of the present disclosure is not limited to these embodiments unless otherwise stated to limit the present disclosure in the following descriptions. Also, “an element A is equal to an element B” as described herein means that the element A and the element B are substantially equal to each other, and the meaning includes manufacturing errors.

#1A-1. Configuration of Organic EL Device

#FIG. 1 is a plan view illustrating an organic EL device 100 according to a first exemplary embodiment. Note that, for convenience of explanation, the description will be made appropriately using an X-axis, a Y-axis, and a Z-axis orthogonal to each other. In addition, a direction along the X-axis is referred to as an X1 direction, and a direction opposed to the X1 direction is referred to as an X2 direction. In addition, a direction along the Y-axis is referred to as a Y1 direction, and a direction opposed to the Y1 direction is referred to as a Y2 direction. A direction along the Z-axis is referred to as a Z1 direction, and a direction opposed to the Z1 direction is referred to as a Z2 direction. Furthermore, viewing in the Z1 direction or the Z2 direction is referred to as “in plan view”. Further, “optical transparency” refers to transparency to visible light, and means that transmittance of visible light may be greater than or equal to 50%. Further, “light reflectivity” refers to reflectivity to visible light, and means that a reflectance of visible light may be greater than or equal to 50%.
