- This light emitting element includes a flexible plate-like portion 100.
- the plate-like portion 100 includes a glass substrate 110 and an organic functional layer formed on one surface side of the glass substrate 110.
- the organic functional layer includes a light emitting layer.
- the configuration of the organic functional layer will be described later in Examples.
- one surface 102 of the plate-like portion 100 is a concave curved surface
- the other surface 101 is a convex curved surface
- the concave surface side of both surfaces of the glass substrate 110 The surface that is positioned is referred to as the first surface 111.

- the thickness of the glass substrate 110 is preferably about 10 ⁇ m to 200 ⁇ m, for example.
- the glass substrate 110 can have a certain degree of flexibility if formed to a certain thickness or less. However, even if the glass substrate 110 is formed to be sufficiently thin, if the glass substrate 110 is bent with a large curvature exceeding the limit (with a small radius of curvature), the glass substrate 110 is cracked starting from a small scratch.
- the breakage (cracking) of the glass substrate 110 As a result of investigation of the breakage (cracking) of the glass substrate 110 by the present inventor, it was found that the progress of cracks due to tensile stress is dominant, and the glass substrate 110 is hardly broken by compressive stress. Therefore, the direction of bending (curving) of the plate-like portion 100 is defined, and in the thickness direction of the glass substrate 110 in a state where the plate-like portion 100 is curved, the region is larger than half of the thickness T of the glass substrate 110. By setting the arrangement of the glass substrate 110 in the thickness direction of the plate-like portion 100 so that the compressive stress is generated, the breakage (cracking) of the glass substrate 110 can be suppressed.
- the center plane C1 shown in FIG. 1 is a plane where tensile stress and compressive stress are balanced in a state where the plate-like portion 100 is curved.

- a compressive stress is applied to the compressive stress generating portion 112 which is a portion of the glass substrate 110 whose distance from the first surface 111 is L or less.

Therefore, compressive stress is generated in a region larger than half of the thickness T of the glass substrate 110 in the thickness direction of the glass substrate 110 in a state where the plate-like portion 100 is curved.
- the center C2 in the thickness direction of the glass substrate 110 (the center C2 of the glass substrate 110 in the thickness direction of the glass substrate 110) is the center in the thickness direction of the plate-like portion 100. (The center of the plate-like part 100 in the thickness direction of the plate-like part 100: not shown) is located on the one surface 102 side of the plate-like part 100.

- the surface that is positioned is referred to as the first surface 111.
- the thickness of the glass substrate 110 is T.
- a compressive stress is applied to a portion of the glass substrate 110 whose distance from the first surface 111 is L (L> T / 2) or less. That is, the arrangement of the glass substrate 110 in the thickness direction of the light emitting element is set so that the compressive stress is applied to the compressive stress generating portion 112 that is a portion having a distance from the first surface 111 of L or less in the glass substrate 110. Thereby, since destruction (cracking) of the glass substrate 110 can be suppressed, the flexibility and reliability of the plate-like portion 100 of the light emitting element can be improved.
- Patent Documents 3 to 5 describe that the stress generated in the inorganic moisture-proof layer or the like is reduced by disposing the inorganic moisture-proof layer or the like at a substantially central portion in the thickness direction of the light emitting element. Is described. For this reason, even when the light emitting element is bent in any direction, an equivalent stress is generated inside the inorganic moisture-proof layer or the like. Since the inorganic moisture-proof film is usually a very thin film having a thickness of 1 ⁇ m or less, the stress generated in the inorganic moisture-proof film can be made extremely small by the configuration described in Patent Documents 3 to 5. However, even if the glass substrate 110 is thin, it has a thickness of, for example, 10 ⁇ m or more.
- the plate-like portion 100 is curved in any direction. Even in such a case, a tensile stress is generated inside the glass substrate 110. Since the glass substrate 110 often has microcracks, chipping of the end face, and the like, and the glass substrate 110 is weaker in tensile stress than the inorganic moisture-proof film, the glass substrate 110 is referred to as an inorganic moisture-proof layer or the like in Patent Documents 3 to 5. It is difficult to obtain a practically sufficient radius of curvature and fracture resistance with a configuration arranged at the same position.
- the bending direction of the light emitting element is defined as one direction, and the distance from the first surface 111 in the glass substrate 110 when the plate-like portion 100 is bent is L (L > T / 2)
- the arrangement of the glass substrate 110 in the thickness direction of the light emitting element is set so that compressive stress is applied to the following portions. Thereby, the tensile stress which generate
- the center C ⁇ b> 2 in the thickness direction of the glass substrate 110 is positioned closer to the one surface 102 of the plate-like part 100 than the center in the thickness direction of the plate-like part 100. It is possible to easily realize a configuration in which compressive stress is applied to the compressive stress generating portion 112 that is a portion having a distance L or less from the first surface 111, and to suppress breakage (cracking) of the glass substrate 110.
