Abstract

A method for making en electro-optic device includes a filling step of ejecting liquid matter containing a solvent and a functional layer-forming material into recesses formed in a substrate to fill the recesses with the liquid matter; and a fixing step of removing a solvent component from the liquid matter to fix the functional layer-forming material in the recesses. In the filling step, the concentration of the functional layer-forming material in the liquid matter filling each recess is changed on the basis of the size of an opening width of the recess.

Claims (10)

1. A method for making an electro-optic device, comprising:

a filling step of ejecting liquid matter containing a solvent and a functional layer-forming material into a plurality of recesses having different opening widths formed in at least one substrate to fill the recesses with the liquid matter; and

a fixing step of removing a solvent component from the liquid matter to fix the functional layer-forming material in the recesses,

wherein, in the filling step, the concentration of the functional layer-forming material in the liquid matter filling each recess is changed on the basis of the size of an opening width of the recess.

2. The method according to claim 1 , wherein, in the filling step, the liquid matter fills each recess until the liquid matter forms a protruding meniscus; and

the liquid matter filling a recess having a relatively small opening width has a functional layer-forming material concentration higher than that of the liquid matter filling a recess having a relatively large opening width.

3. The method according to claim 1 , wherein the concentration of the functional layer-forming material in the liquid matter filling the recesses is changed on the basis of the size of the opening width by using a plurality of types of liquid matter having different functional layer-forming material concentrations and adjusting the balance of amounts of the plurality of types of liquid matter to be ejected into each recess according to the size of the opening width.

4. The method according to claim 1 , wherein the concentration of the functional layer-forming material in the liquid matter filling the recesses is changed on the basis of the size of the opening width by adjusting the functional layer-forming material concentration of the liquid matter to be ejected to each recess according to the size of the opening width.

5. The method according to claim 1 , wherein the recesses having different opening widths are formed in different substrates.

6. The method according to claim 1 , wherein the functional layer-forming material is used to form an organic functional layer of an organic electroluminescent element on the substrate.
