    摘要： A coating method and a coating apparatus which is suitable for stably forming a coating on the surface of a flat sheet member, and a method of manufacturing coated sheets such as a color filter. The coating method comprises the steps of supplying a coating liquid to a coating liquid discharging apparatus having a coating liquid discharging slit by means of a coating liquid feeder, relatively moving at least either the coating liquid discharging apparatus or a member to be coated and forming a coating having a predetermined thickness on the member. A coating start portion of the member is stopped at a place at which it opposes the coating liquid discharging slit of the coating liquid discharging apparatus, and discharge of the coating liquid from the coating liquid discharging slit is started. After a coating liquid bead which is in touch with both of the front end opening of the coating liquid discharging slit and the coating start portion of the member is formed, relative movement of at least either the coating liquid discharging apparatus or the member is started. By the coating method, discharge of the coating liquid is started when the member stops relative to the coating liquid discharging slit, and after the formation of the coating liquid bead is confirmed, the member is relatively moved in a state that the coating liquid bead remains stable. Therefore, the coating start position can be correctly determined, and a coating can be formed highly accurately.

    摘要翻译： 本发明提供一种涂布方法和涂布装置，该涂布方法和涂布装置适合于在平板状部件的表面上稳定地形成涂层，以及制造诸如滤色器的涂布片材的方法。 该涂布方法包括以下步骤：通过涂布液供给装置将涂布液供给至具有涂布液排放狭缝的涂布液排放装置，使涂布液排放装置或待涂布构件中的至少一个相对移动并形成 涂层在构件上具有预定的厚度。 该部件的涂布开始部停止在与涂布液排放装置的涂布液排放狭缝相对的位置处，并且开始从涂布液排放狭缝排放涂布液。 在形成与涂布液排放狭缝的前端开口和构件的涂布开始部两者都接触的涂布液珠之后，开始涂布液排放装置或构件中的至少一个的相对移动。 通过涂布方法，当部件相对于涂布液排出狭缝停止时，开始涂布液的排出，并且在确认形成涂布液珠之后，部件以残留涂布液珠的状态相对移动 稳定。 因此，能够正确地确定涂布开始位置，能够高精度地形成涂布。
