Previous reports indicated that Apple and Japan Display had been in talks for a partnership for a $1.7 billion plant. As with the previous reports, Apple is said to be making an investment in this plant, according to Reuters:

The company did not name Apple, in line with its policy of not identifying clients. A person familiar with the matter said Apple would also invest an unspecified amount in the plant, which would further the Japanese screen maker's aim of becoming the primary supplier of high-tech screens for iPhones.

The plant is set to open in 2016, and should boost Japan Display's LCD production capacity by 20%.

Japan Display isn't the only company said to be building a plant for Apple. In November 2014, it was reported that Foxconn was building a display plant with a single client in mind. In both cases, it seems likely that Apple is the client. Few other companies could generate the demand that would require these dedicated facilities.
