FLEXIBLE SUBSTRATE MEMBER AND LIGHT EMITTING DEVICE

摘要

A flexible substrate member which can prevent breakage due to bending, regardless of a shape of a metal pattern, and a light emitting device which employs the flexible substrate. The flexible substrate member includes a plurality of metal wirings disposed on an insulating substrate which are spaced apart from each other via a groove portion. The groove portion includes an intersection region where a first groove portion and a second groove portion are intersected. The metal wirings includes a first metal wiring and a second metal wiring which are demarcated via the first groove portion in the intersection region, and a third metal wiring which is demarcated via the second groove portion with respect to the first metal wiring and the second metal wiring. The third metal wiring includes a projection which projects on an extension line of the first groove portion.
