DIE COATER, MOUTH PIECE FOR DIE COATER, DIE-COATING METHOD EMPLOYING DIE COATER, AND OPTICAL ELEMENT AND LIQUID CRYSTAL DISPLAY PREPARED BY USING DIE COATER

摘要

PROBLEM TO BE SOLVED: To provide a die coater and a die-coating method capable of forming a thinner coating film with a high accuracy extensively suppressing its unevenness by solving the problem of unevenness arising in a coating film upon preparing an optical element using a die-coater, and an optical element and a liquid crystal display prepared by using the die-coater.;SOLUTION: The die coater 1, constituted of a die main body 2 constructed in a manner movable relative to a specified substrate and equipped with a mouth piece 4 comprising a slit 8 with a sufficient opening width for ejecting a paint and a slot 9 extending up to the slit 8 from a manifold 7 to form a paint path, is characterized by comprising a heating mechanism 3 disposed at a specified position surrounding the slot 9 for heating the mouth piece 4. The die coater 1 enables a die-coating method to form a coating film with a high accuracy by extensively suppressing its unevenness and hence enables the same to prepare an optical element and a liquid crystal display having a high accuracy of thickness.;COPYRIGHT: (C)2009,JPO&INPIT
