Tokyo — Matsushita and Hitachi have reached an agreement to supply each other with key large plasma-display-panel screen sizes, the companies said in a joint statement.

Under the agreement, Matsushita, which markets the Panasonic brand, will supply Hitachi with 103-inch panels starting this year, while Hitachi will sell Matsushita forthcoming 85-inch panels beginning in the next fiscal year.

Hitachi will introduce its first 85-inch panel in mid-2008.
