Abstract

A light emitting device includes a flexible substrate, at least one light emitting element, a sealing resin and an adhesion layer. The flexible substrate includes a flexible base member and a plurality of wiring portions disposed on one surface of the base member. At least one light emitting element is arranged on a first surface of the flexible substrate and electrically connected to the wiring portions. The sealing resin seals the light emitting element. The adhesion layer is arranged on a second surface of the flexible substrate different from the first surface of the flexible substrate. The adhesion layer has a non-adhesive region corresponding at least to a region on the first surface where the at least one light emitting element is arranged. The non-adhesive region is covered with a non-adhesive layer.

Claims (7)

1. A light emitting device comprising:

a flexible substrate including a flexible base member and a plurality of wiring portions disposed on one surface of the base member;

at least one light emitting element arranged on a first surface of the flexible substrate and electrically connected to the wiring portions;

a sealing resin sealing the light emitting element; and

an adhesion layer arranged on a second surface of the flexible substrate different from the first surface of the flexible substrate, the adhesion layer having a non-adhesive region corresponding at least to a region on the first surface where the at least one light emitting element is arranged, the non-adhesive region being covered with a non-adhesive layer.

2. The light emitting device according to claim 1 , wherein the non-adhesive region has an area 1 to 100 times that of the light emitting element.

3. The light emitting device according to claim 1 , further comprising a support member disposed on a side of the second surface of the flexible substrate, the support member being arranged so that the support member does not adhere to the non-adhesive region of the adhesion layer.
