Abstract

　L'invention concerne un procédé grâce auquel on peut fabriquer d'une manière appropriée une plaque de verre incurvée pourvue d'un film antireflet ayant des propriétés antireflet élevées. Dans la présente invention, une étape de formation d'un film est réalisée pour la formation d'un film antireflet (11) ayant une température de transition vitreuse (Tg) supérieure à celle d'une plaque de verre plane (10) sur une face principale (10b) de la plaque de verre plane (10), et la fabrication d'une plaque de verre plane (12) pourvue d'un film antireflet. Dans la présente invention, une étape de déformation est réalisée pour déformer la plaque de verre plane (12) pourvue du film antireflet, par chauffage de celle-ci, et fabriquer une plaque de verre incurvée (14) pourvue du film antireflet.
