Application method, applicator, optical member, and optical device

Abstract

An applicator including a liquid discharge head for discharging a treatment liquid in droplet form, and a discharge control device for controlling the discharge of droplets from the liquid discharge head. The discharge control device divides a surface of a member into a plurality of regions according to the shape of the surface, and controls the application quantity for each region.

1 . An applicator for applying a treatment liquid onto a surface of a member, comprising: 
 a liquid discharge head for discharging the treatment liquid in droplet form; and    a discharge control device for control the discharge of droplets from the liquid discharge head,    wherein the discharge control device divides the surface of the member into a plurality of regions according to the shape of the surface, and controls the application quantity for each region.    
   
   
       2 . An applicator according to  claim 1 , wherein the discharge control device controls the application quantity by varying at least one of the volume or weight per droplet of the liquid from the liquid discharge head and the landing intervals of droplets.  
   
   
       3 . An application method according to  claim 1  or  2 , wherein the treatment liquid is repeatedly applied by the discharge control device onto the surface of the member a plurality of times, and a number of repetitions of application is set for each of the plurality of regions.  
   
   
       4 . An optical member having a surface onto which a treatment liquid has been applied with an applicator as set forth in claims  1  or  2 .  
   
   
       5 . An optical device including the optical member as set forth in  claim 4.
