Abstract

Official abstract text for this publication.

The width W1 of a groove ( 5 a ) is formed narrower than the width W2 of a groove ( 6 a ). The width W2 of the groove ( 6 a ) is formed at a prescribed width such that a sealing material ( 8 ) that overflows the groove ( 5 a ) can be formed along the groove ( 6 a ). The sealing material ( 8 ) spreads across the entirety of the groove ( 5 a ) and the groove ( 6 a ) when a color filter substrate ( 2 ) and an active matrix substrate ( 3 ) are bonded together. The groove ( 5 a ) is formed so as to be positioned within the groove ( 6 a ) in a plan view.
