| 発明の概要（英語） |
(US7727686) To provide a method of making a film of organic material excellent in moisture barrier property and/or oxygen barrier property and also to provide an electronic device excellent in long term stability, in which the film obtained by such film making method is utilized to form a protective film for protecting an electronic device, and particularly an organic electronic device, to avoid deterioration of the performance, which would otherwise be brought about by moisture and oxygen in the atmosphere. The film is formed by depositing and solidifying, on a substrate, an evaporant formed by irradiating a liquid crystal polymer capable of exhibiting an optical anisotropy with pulsed laser. |

[claim1] 1. A film making method comprising: forming a liquid crystal polymer evaporant by irradiating a thermotropic liquid crystal polymer capable of exhibiting optical anisotropy and having a melting point of 250 deg. C. to 350 deg. C. with a pulsed laser to evaporate the liquid crystal polymer, and depositing and solidifying the evaporant on a surface to form a film of the thermotropic liquid crystal polymer on the surface. [claim2] 2. A film formed by the method of claim 1. [claim3] 3. A laminate comprising the film recited in claim 2 on a surface. [claim4] 4. An electronic device comprising the film recited in claim 2 as a protective film. [claim5] 5. The electronic device as claimed in claim 4, wherein the electronic device is an organic electroluminescent element. [claim6] 6. The electronic device as claimed in claim 4, wherein the electronic device is an organic field-effect transistor element. [claim7] 7. The method of claim 1, wherein said surface is a surface of an electronic device. [claim8] 8. The method as claimed in claim 7, wherein the electronic device is an organic electroluminescent element. [claim9] 9. The method as claimed in claim 7, wherein the electronic device is an organic field-effect transistor element. [claim10] 10. The method of claim 1, wherein the thickness of the film of the thermotropic liquid crystal polymer on the surface is less than 1 mu m. [claim11] 11. The method of claim 10, wherein the thickness of the film of the thermotropic liquid crystal polymer on the surface is not less than 30 nm. [claim12] 12. The method of claim 1, wherein the thermotropic liquid crystal polymer irradiated with a pulsed laser is in the form of a film, and is irradiated at a wavelength of 200-1200 nm with a pulsed laser that generates energies within the range of 0.1 to 3.0 J/cm2. [claim13] 13. The method of claim 11, wherein the thermotropic liquid crystal polymer irradiated with a pulsed laser is in the form of a film, and is irradiated at a wavelength of 200-1200 nm with a pulsed laser that generates energies within the range of 0.1 to 3.0 J/cm2. |
