Apple Inc. plans to invest $100 million (10.7 billion yen) in Japan Display Inc. (JDI), a much-needed infusion for the struggling liquid crystal display manufacturer that just saw a bailout plan collapse, sources said.

California-based Apple is a major customer of JDI and accounts for 60 percent of its sales.

The investment of $100 million comes on top of about 100 billion yen that JDI is borrowing from Apple.

The two companies agreed in May to extend JDI’s repayment period by halving the Tokyo-based company’s payments for each quarter.

JDI, which started operations in 2012 by combining the LCD businesses of Toshiba Corp., Sony Corp. and Hitachi Ltd., intends to restructure its management through the support from Apple, the sources said.

According to the sources, Apple initially considered investing the money in JDI through TPK Holding Co., a leading electronics parts manufacturer in Taiwan that was one of the companies that formed an alliance to rescue JDI.

However, TPK withdrew from the bailout negotiations.

Apple now plans to make the investment through Harvest Group, a major Chinese investment firm that was another partner in the bailout plan.

Harvest and a Hong Kong investment fund, Oasis Management Co., are also considering investing a total of 58.2 billion yen in JDI. The two companies indicated that they would complete the procedures necessary for the investment by June 27.

Attention is now focused on whether Apple’s support will make it easier for Harvest and Oasis to decide to invest in JDI.
