    Abstract: A cell culture substrate includes a base, a first segment disposed on the base and occupying a part of one surface of the cell culture substrate, and a second segment disposed on the base and occupying another part of the one surface. The second segment is formed of a metal material and thus has a relatively higher surface free energy than the first segment formed of an inorganic material. The second segment is disposed such that a percentage of an area of the second segment in a total area of the first segment and the second segment increases in a gradation direction (first direction) along the one surface.

  • Patent number: 7075603
    Abstract: In a semi-transmission type liquid crystal display and a method for fabricating the same, a reflective electrode such as aluminum layer and a transparent electrode such as ITO film are used to form a pixel electrode that is provided on an organic film having an uneven surface. In order to effectively restrict the battery effect between a reflective electrode and a transparent electrode, a surface of the organic film is put in a plasma-processing and then is washed by a washing liquid. Thereafter, the transparent electrode is formed and then the reflective electrode such as a double layer electrode of the aluminum layer and the molybdenum layer are formed.

  • Patent number: 6972821
    Abstract: An active-matrix addressing LCD device that suppresses effectively the off leakage current induced by the charge-up of the spacers placed over the TFTs. The device comprises (a) a first substrate having switching elements; (b) a second substrate coupled with the first substrate in such a way as to form a gap with spacers between the first and second substrates; the spacers being distributed in the gap; (c) a liquid crystal confined in the gap; and (d) protrusions formed in overlapping areas with the switching elements; each of the protrusions being protruded in a direction that narrows the gap. The spacers distributed in the gap are likely to be shifted away from the overlapping areas due to the protrusions.

  • Patent number: 6891196
    Abstract: An active matrix substrate of a channel protection type having a gate electrode, a drain electrode and a pixel electrode is isolated in each layer by insulating films. The active matrix substrate is to be prepared by four masks. A gate electrode layer, a gate insulating film and an a-Si layer are processed to the same shape on a transparent insulating substrate to form a gate electrode layer and a TFF area. A drain electrode layer is formed by a first passivation film with the first passivation film formed as an upper layer. In a second passivation film, formed above the first passivation film, are bored a first opening through the first and second passivation films and a second opening through the second passivation film. A wiring connection layer is formed by ITO provided as an uppermost layer.
