An organic electron transport layer has at least one dopant for increasing the n-conductivity of the organic layer. The dopant is selected from the group of salts of cyclopentadiene compounds according to formula 1, wherein the substituents R1 to R2 are independently selected from the group containing H, -D, halogen, CN, NO2, OH, amine, ether, thioether, alkyl, cycloalkyl, acrylic, vinyl, allyl, aromatics, fused aromatics and heteroaromatics.

A flexible array substrate structure and manufacturing method thereof are disclosed, in which the patterning process of an organic semi-conductive layer is achieved by using the inside wall of the opening of a color film layer as a bank, so that one mask can be saved. Also, a process for manufacturing a device can be simplified by an improved device structure, so that the flexible array substrate structure of the invention can be obtained by only using four masks.

The present invention relates to a carbon nanotube interlayer, a manufacturing method thereof, and a thin film transistor using the same. More specifically, the present invention provides a carbon nanotube interlayer, a manufacturing method thereof, and a thin film transistor using the same, where the carbon nanotube interlayer is a layer constituting an organic thin film transistor and comprising a conjugated polymer and a single-walled carbon nanotube between an organic semiconductor layer and a source/drain electrode. The conjugated polymer selectively wraps the single-walled carbon nanotube having semiconducting properties.

A technique of manufacturing a display device with high productivity is provided. In addition, a high-definition display device with high color purity is provided. By adjusting the optical path length between an electrode having a reflective property and a light-emitting layer by the central wavelength of a wavelength range of light passing through a color filter layer, the high-definition display device with high color purity is provided without performing selective deposition of light-emitting layers. In a light-emitting element, a plurality of light-emitting layers emitting light of different colors are stacked. The closer the light-emitting layer is positioned to the electrode having a reflective property, the shorter the wavelength of light emitted from the light-emitting layer is.
