    摘要: A unit pixel (10) includes a plurality of current controlling elements (Tr2a–Tr2d) having controlling terminal and connected to a single EL element (11), and switching elements (Tr1a–Tr1d) provided to the respective current controlling elements in order to switch between application and cutoff of a digital image signal with respect to the controlling terminals in accordance with the condition of a scanning signal. Each of the current controlling elements is controlled by a voltage of the digital image signal so as to take an OFF state for cutting off a supply of a driving current to the EL element or an ON state for supplying the EL element with a driving current corresponding to the voltage of the digital image signal, and a value of the current flowing in the EL element is the sum value of currents supplied from the respective current controlling elements in the ON state. 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: 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.
