It is possible to manufacture a large-size, high-accuracy organic EL display using a plastic substrate and an organic EL display using a roll-shaped long plastic substrate. The organic EL display includes an organic EL device A having at least a lower electrode, an organic layer including at least a light emitting layer, and an upper electrodeand a thin film transistor B on a transparent plastic substrate, a source electrode or drain electrode of the thin film transistor B is connected to the lower electrode, the plastic substratehas a gas barrier layer, the thin film transistor B is formed on the gas barrier layer, the thin film transistor B includes an active layercontaining a non-metallic element which a mixture of oxygen (O) and nitrogen (N) and has a ratio of N to O (N number density/O number density) from 0 to 2, and the organic EL device A is formed at least on the gas barrier layeror one the thin film transistor B.

Organic EL display and method of manufacturing organic EL display

A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 &#x3bc;m to 200 &#x3bc;m, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/&#xb0; C. or less. Furthermore, it more preferably gives a variation of &#xb1;5% or less in mechanical and optical properties to a thermal history at 200&#xb0; C.

To provide a device for pasting a film exhibiting dichroism and a film exhibiting birefringence at an arbitrary angle with high precision. The device for pasting a film exhibiting dichroism and a film exhibiting birefringence at an arbitrary angle comprises a detector for detecting the angle of an axis where absorption is maximum or minimum in the plane of a film exhibiting dichroism, and a detector for detecting the slow axis in the plane of a film exhibiting birefringence. An angle between the film exhibiting dichroism and the film exhibiting birefringence is controlled using the detector for a film exhibiting dichroism and the detector for a film exhibiting birefringence.

The present invention provides a process for continuously producing a polymer sheet having an excellent surface smoothness, an apparatus for producing such a polymer sheet, and an optical polymer sheet produced by such a process. The process for producing a polymer sheet comprises coating or laminating, on a polymer base sheet, an ultraviolet-curing resin composition, adhering the coated or laminated polymer base sheet to a member having a smooth surface whose maximum surface roughness (Rmax) satisfies Rmax&lE;0.1 &mgr;m, in a state that the ultraviolet-curing resin composition is soft, and applying an ultraviolet light to transfer smoothness of the smooth surface of the member onto the polymer base sheet.
