Flexible printed circuit board, planar light source apparatus, display apparatus, and electronic device
A flexible printed circuit board on which a first electronic component and a second electronic component are to be mounted adjacent to each other has a first land for soldering a terminal of the first electronic component on a side adjacent to the second electronic component, and a second land for soldering a terminal of the second electronic component on a side adjacent to the first electronic component. The first land and the second land are connected by a wire extending outside of an inter-land region that is an approximately belt-shaped region formed by connecting end portions in a width direction or end portions in a thickness direction of the first land and the second land in a straight line.

wherein the first land and the second land are connected by a wire extending outside of an inter-land region that is an approximately belt-shaped region formed by connecting end portions in a width direction or end portions in a thickness direction of the first land and the second land in a straight line,
wherein a front surface of the flexible printed circuit board is covered by a cover lay,
wherein an opening is formed on at least a portion of the cover lay that corresponds to the inter-land region, and
wherein the opening extends continuously across the inter-land region in an adjacency direction of the first and second electronic components.
2. The flexible printed circuit board according to claim 1 ,
wherein the wire branches, and the branched wire extends outside of the inter-land region.
3. The flexible printed circuit board according to claim 1 ,
wherein the flexible printed circuit board has a double-sided structure or a multi-layered structure, and
wherein the wire goes through a surface or a layer that is different from a surface or layer on which the first land and the second land are provided, so as to connect the first land and the second land.
