Abstract: The color filter of the present invention comprises ink films colored by ink drops 140 inside openings 111 enclosed by banks 112 demarcated and formed on a substrate 110. The banks 112 have a laminar structure comprising a metal film 120 and a photosensitive organic thin film 130 from the substrate 110 side. The inks should contain a solvent having a high boiling point. The bank layer may also be configured so that the peripheral edges of the bottom surface thereof are positioned inside from the peripheral edges of the light blocking layers, so that the light blocking layers have exposed surfaces on the upper surface thereof where the bank layer is not superimposed. Thus color filters can be provided which exhibit outstanding contrast without coloring irregularities.

Abstract: The invention ensures that a liquid is placed in a predetermined region (without being placed in an adjacent region) with a uniform thickness in the region, when a light emitting layer constituting an organic EL element is placed by, for example, ink jet process. Thin SiO2 film pattern having an opening is formed on an ITO electrode. Next, ultrathin organic film pattern having an opening is formed on a thin SiO2 film pattern. The surface of the ultrathin organic film pattern becomes repellent to liquid. Hole transporting layer is formed in the opening of the ultrathin organic film pattern, and then liquid containing a material for the formation of light emitting layer is discharged thereon by ink jet process. Fluid does not remain on the surface of the ultrathin organic film pattern and instead enters the opening of the ultrathin organic film pattern.

Abstract: To ensure that a liquid is placed in a predetermined region (without being placed in an adjacent region) with a uniform thickness in the region, when a light emitting layer constituting an organic EL element is placed by, for example, ink jet process. Thin SiO2 film pattern 3 having opening 3ais formed on ITO electrode 2. Next, ultrathin organic film pattern 41 having opening 4b is formed on thin SiO2 film pattern 3. The surface of ultrathin organic film pattern 41 becomes repellent to liquid. Hole transporting layer 61 is formed in opening 4b, and then liquid 7 containing a material for the formation of light emitting layer is discharged thereon by ink jet process. Fluid 7 does not remain on the surface of ultrathin organic film pattern 41 but enters opening 4b.
