Embodiment Construction

[0057] Next, the liquid droplet ejection device, the manufacturing method of the electro-optic device, the electro-optic device and the electronic equipment of the present invention will be described with reference to the drawings. The inkjet head (functional droplet ejection head) of an inkjet printer can eject tiny ink droplets (functional liquid droplets) into dots with high precision, so for example, by using a special Liquids such as inks and luminescent or photosensitive values ​​are expected to be used in the field of manufacturing various devices.

[0058] The droplet ejection device of this embodiment forms the required liquid droplet ejection heads on the substrate by appropriately replacing and using multiple functional droplet ejection heads with different specifications or different functional liquids introduced in the device. The film-forming part (details are described later).

[0059] Such as figure 1 As shown, the droplet ejection device 1 of the embodiment ...

Abstract

A liquid droplet ejection apparatus is made up of: a function liquid droplet ejection head (10) which is disposed in parallel with the surface of a nozzle of the ejection head (10) relative to a workpiece (W); a device (15, 16) for measuring a workpiece gap between the surface of the workpiece (W) and the surface of the nozzle; and a device (32) for adjusting the workpiece gap by relatively moving in the vertical direction the function liquid ejection head (10) and the workpiece (W) based on the result of measurement by the device (15, 16) for measuring the gap. The workpiece gap between the workpiece (W) and the function liquid droplet ejection head (10) is automatically fine-adjusted.

Description

technical field [0001] The present invention relates to a droplet ejection device that ejects a functional liquid onto a workpiece such as a substrate through a functional droplet ejection head represented by an inkjet head, and particularly relates to a workpiece gap that can be adjusted between the workpiece and the functional droplet ejection head. A liquid droplet ejection device, a method for manufacturing an electro-optical device, an electro-optical device, and an electronic instrument. Background technique [0002] Conventional droplet ejection devices such as inkjet printers (color printers) operate by relatively scanning a functional droplet ejection head (inkjet head) on an object to be ejected (workpiece) such as printing paper. The workpiece is processed by performing ejection drive of liquid droplets and selectively ejecting the functional liquid onto the object to be ejected. At this time, in order to manage the flight bending and attachment diameter of funct...
