|1. (WO2017199394) LED ELEMENT SUBSTRATE AND LED DISPLAY DEVICE|
|Applicants:||DAI NIPPON PRINTING CO., LTD.
|Title:||LED ELEMENT SUBSTRATE AND LED DISPLAY DEVICE|
The present invention addresses the problem of reducing, in a flexible substrate-type LED element substrate, the risk of bending damage caused by the flexibility of a resin substrate and differences in flexural modulus between the resin substrate and metal wiring. An LED element substrate 1 is provided with a resin substrate 11 comprising a flexible resin film, and a metal wiring section 13 in which LED elements 2 arranged in a matrix shape are conductively formed on the resin substrate 11. The metal wiring section 13 comprises a plurality of circular or polygonal conductive plate sections 131 disposed on the resin substrate 11. Any given insulated slit section 132, which is a non-conductive area between two adjacent conductive plates 131, is not in line with any other adjacent insulating slit section 132.
