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.

摘要： A number of minuscule LDD thin film transistors with high precision are arranged on a substrate for use in a liquid crystal display apparatus or other similar devices. The gate electrode is used as a mask at the time of injecting impurities into the semiconductor layer. To realize an LDD structure, the impurities are injected in two installments. The size of the gate electrode is changed in accordance with the length of the LDD regions between the first and second injections. The size of the gate electrode is changed by means of metal oxidation or dry etching. For precision dry etching of the gate electrode, various ideas are put into forming the photo resist.

Based on a combination of the current controlling elements in the ON state, the current supplied to the EL element is controlled to be a value corresponding to the gradation.

摘要： A semiconductor device provided with a thin-film transistor comprising a polycrystalline semiconductor thin film (2) formed on an insulating substrate (100). The semiconductor device comprises a channel region (80), a source region (91), and a drain region (92), each disposed on both sides of the channel region (80) in the semiconductor thin film (100). The channel region (90) comprises both a first conductive impurity and a second conductive impurity, the conductive type of the second conductive impurity being opposite the conductive type of the first conductive impurity, and is structured by layering a first layer in which the first conductive impurity and the second conductive impurity are canceled and a second layer in which either of the first conductive impurity or the second conductive impurity is dominant, wherein a gate electrode (4) is formed so as to face the first layer (2a) via an insulating film (3). The source region (91) and the drain region (92) have a conductive type that is opposite the conductive type that is dominant in the second layer (2b). This structure reduces OFF-current and makes it easy to control threshold voltage.

摘要： A spatial light modulator and a neural network circuit are disclosed. The modulator is used in pattern recognition and has an arrangement in which a photoconductive layer held between conductive electrodes is connected in series to a liquid crystal cell including a liquid crystal layer held between two opposite electrodes. Setting the rate between the area of the photoconductive layer and the area of at least one of the opposite electrodes between which the liquid crystal layer is disposed, provides a highly efficient reflective and transmissive spatial light modulator of a simple structure. Both reflective and transmissive spatial light modulating elements are applied to a neurocomputer or the like.
