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. |

1. A flexible substrate member comprising:
an insulating substrate member; a groove portion including a first groove portion, a second groove portion, and an intersection region; the intersection region disposed where the first groove portion and the second groove portion intersect; and a plurality of metal wiring including a first metal wiring, a second metal wiring, and a third metal wiring, the first metal wiring separated from the second metal wiring by the first groove portion in the intersection region with the first metal wiring defining a first edge of the first groove portion and the second metal wiring defining a second edge of the first groove portion in the intersection region, the third metal wiring separated from the first metal wiring and the second metal wiring by the second groove portion, the third metal wiring includes a projection projecting toward and/or away from the first groove portion in a plan view, and at least a part of the projection being arranged between a first extension line of the first edge of the first groove extending toward the third metal wiring and a second extension line of the second edge of the first groove extending toward the third metal wiring in the plan view. |
