  • Patent number: 8294853
    Abstract: An object of the invention is to accurately and easily manufacture a color filter. A method of manufacturing a color filter comprises: a first step of forming a first rib (220) forming a light shield layer and a second rib (230) having a smaller height than the first rib (220) in pattern on a base layer (1) by means of a photolithography method; a second step of forming a step-forming layer (4) by dripping an optical transmissive material into an area defined by the first and second ribs (220, 230) by means of ink-jet technique; and a third step of forming a coloring layer by dripping an optical coloring material (5) into an area defined by the first rib (220) by means of ink-jet technique after forming the step-forming layer (4).

  • Patent number: 7928948
    Abstract: The invention aims at preventing an occurrence of artefacts while reducing power consumption. A matrix addressing method for alternately driving pixels. The frame period of the images is formed by successively sequencing on a time series a plurality of block periods, the block periods each being composed of a first half block being a period for successively sequencing on a time series application timings of the pixel voltages for one or more row electrodes to be provided with one polarity, the second half block being a period for successively sequencing on a time series application timings of the pixel voltages for one or more row electrodes to be provided with the other polarity. Ones of even-numbered row electrodes and odd-numbered row electrodes in arrangement order on the display screen are selected in the first half block. The others spatially adjoining the ones are selected in the second half block.
