  • Patent number: 11914254
    Abstract: A liquid crystal display device comprising a TFT substrate having pixels each including a common electrode formed on an organic passivation film, an interlayer insulating film formed so as to cover the common electrode, a pixel electrode having a slit and formed on the interlayer insulating film, a through-hole formed in the organic passivation film and the interlayer insulating film, and a source electrode electrically conducted to the pixel electrode via the through-hole. A taper angle at a depth of D/2 of the through-hole is equal to or more than 50 degrees. The pixel electrode covers part of a side wall of the through-hole but does not cover the remaining part of the side wall of the through-hole. This configuration facilitates the alignment film material to flow into the through-hole, thereby solving a thickness unevenness of the alignment film in vicinity of the through-hole.

  • Patent number: 11915920
    Abstract: The present invention provides a simpler method for sharpening a tip of an emitter. In addition, the present invention provides an emitter including a nanoneedle made of a single crystal material, an emitter including a nanowire made of a single crystal material such as hafnium carbide (HfC), both of which stably emit electrons with high efficiency, and an electron gun and an electronic device using any one of these emitters. A method for manufacturing the emitter according to an embodiment of the present invention comprises processing a single crystal material in a vacuum using a focused ion beam to form an end of the single crystal material, through which electrons are to be emitted, into a tapered shape, wherein the processing is performed in an environment in which a periphery of the single crystal material fixed to a support is opened.

  • Patent number: 11906857
    Abstract: In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.
