摘要： An organic EL display panel includes a substrate, pixel electrodes, a common electrode, signal lines, power supply lines, thin-film transistors, scan lines, organic EL elements and storage capacitors. To obtain a full color image by light emissions of the organic EL elements, red, green and blue emitters are patterned correspondently with the pixel electrodes and arranged in this order along the gate line direction. The emitters are patterned such that each pair of the red, green and blue emitters which are adjacent to each other along the gate line direction overlap each other to define a light-emitting layer overlap region, where colors of light components which exit the organic EL elements and pass through the emitters are mixed, between the adjacent organic EL elements arranged along the gate line direction. At least one of the thin-film transistor and the storage capacitor is arranged in the light-emitting layer overlap region.

摘要： An object of the present invention is, by eliminating a driver IC from the components of an liquid crystal display, to achieve a cost reduction, to eliminate a manufacturing step of mounting the driver IC onto an array substrate, and to reduce a thickness of the liquid crystal display. A driver circuit for an active matrix liquid crystal display comprises a resistive dividing type digital-to-analog converter circuit (DAC). An analog output voltage from the DAC is amplified by a signal amplifier element, and a liquid crystal element is driven by the amplified analog output voltage. The driver circuit is characterized in that a resistance element R is formed in an n+ layer of p-Si on an array substrate of the liquid crystal display, and a switching element Tr and a signal amplifier element are also formed on the array substrate.

Each of the unit pixels 10 has an EL element 11, a switching transistor Tr1, a driver transistor Tr2, and an auxiliary capacitor 13. The auxiliary capacitor 13 has electrodes, one connected to a gate electrode of the transistor Tr2 and the other to a next gate line GL. The gate line driver circuit 4 outputs, via the next gate line GL, blanking signals for forcibly stopping a light-emitting state of the EL elements 11, within hold times in which the voltages written to the gate electrodes of the transistors Tr2 are held. With such a configuration, a blanking period where the EL elements do not emit light, is inserted in one frame.

摘要： A method of production of active matrix display substrates using thin film transistors and more particularly to a method for production of substrates for liquid-crystal display use. The active matrix substrate using the thin film transistor is produced by the mask processes of smaller number. The process of the present invention can reduce the number of the masks, by one, of the active matrix substrate using the inverted staggered thin film transistor which requires the masks from five levels to six levels. Further improvements reduce the number of the masks to four levels from three levels, thus contributing greatly towards lower cost, improved yield.
