DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 to the registration statement on Form S-3, File No. 333-134921 (the “Registration Statement”), which was originally filed on June 9, 2006, is being filed to terminate the Registration Statement and deregister unsold shares of common stock of the registrant, Cambridge Display Technology, Inc.

On September 19, 2007, pursuant to that certain agreement and plan of merger, dated as of July 31, 2007, the registrant became a wholly-owned subsidiary of Sumitomo Chemical Co., Ltd. (the “Merger”) and shares of the registrant’s common stock ceased to be quoted on the Nasdaq Global Market and were deregistered under the Securities Exchange Act of 1934. On September 19, 2007, the registrant also filed a certification and notice of termination on Form 15 with respect to the registrant’s common stock. As a result of the Merger, the registrant has terminated all offerings of its common stock under its existing registration statements (including the Registration Statement).

Accordingly, pursuant to the registrant’s undertaking in Item 17 of Part II of the Registration Statement, this Post-Effective Amendment No. 1 to the Registration Statement is being filed to deregister, as of the effectiveness of this Post-Effective Amendment, all shares of common stock registered under the Registration Statement that were not sold prior to the date hereof.
