Document Type and Number:
WIPO Patent Application WO/2020/174879
Kind Code:
A1
Abstract:
This light emission element substrate comprises: a substrate (1) having a mounting surface (1a) on which a first light emission element (14a) and a second light emission element (14b) are mounted; and a pixel unit (15) that is disposed on the mounting surface (1a) side and includes a driving circuit (32) and a first driving line (25a) and a second driving line (25b) connected in parallel to the driving circuit (32). The first driving line (25a) is a normal driving line, the second driving line (25b) is a redundant drive line, and a first positive electrode pad (20pa) and a first negative electrode pad (20na) connected to the first light emission element (14a) are arranged on the mounting surface (1a) side. One among the first positive electrode pad (20pa) and the first negative electrode pad (20na) is connected to the first driving line (25a), and the second positive electrode pad (20pb) and the second negative electrode pad (20nb) connected to the second light emission element (14b) are arranged on the mounting surface (1a) side. One among the second positive electrode pad (20pb) and the second negative electrode pad (20nb) is connected to the second driving line (25b).
