摘要： An in-plane-switching liquid crystal display unit has a two-dimensional matrix of pixel regions each including a first auxiliary region and a second auxiliary region. When no electric field is applied, liquid crystal molecules in the first and second auxiliary regions are directed in respective orientations that lie at 90° with respect to each other. When a voltage is applied, the liquid crystal molecules are rotated in the same direction while maintaining their orientations in the first and second auxiliary regions at 90° with respect to each other. Alternatively, the liquid crystal molecules in the first and second auxiliary regions are directed in the same orientation when no electric field is applied, and when a voltage is applied, the liquid crystal molecules are rotated 15 opposite directions while maintaining their orientations in symmetric relationship.

摘要： After a fluid film is formed by supplying a material with fluidity to the surface of a substrate formed with a stepped layer, the fluid film is pressed against the substrate by a pressing member having a planar pressing surface so that the surface of the fluid film is planarized. The fluid film is heated in this state and thereby solidified to form a solidified film having a planar surface.

摘要： A liquid crystal display device comprises shield means for shielding an electric field generated from a data line. For example, a common electrode is used as the shielding means in an IPS (In-Plane Switching) rode in which an electric field is applied in a direction respecting parallel to the substrates. Specifically, the common electrode is provided closer to the liquid crystal layer than the data line so that the common electrode covers the data line. As a result, the leak electric field from the data line is shielded by the common electrode. Therefore, the leak electric field does not adversely influence a liquid crystal layer. Consequently, the light shield area for the data line is unnecessary. This increases the aperture ratio.

摘要： By etching, a first groove and a second groove are formed in a silicon substrate. Surfaces of the side walls of these grooves have a surface orientation of (111). The first and second grooves sandwich a silicon thin plate therebetween, which is formed as a part of the silicon substrate. The silicon thin plate is sufficiently thin so as to act as a quantum well. Further, a pair of silicon oxide films acting as tunneling barriers are formed on the surfaces of the side walls of the silicon thin plate, thus forming a double barrier structure. In addition, a pair of polysilicon electrodes are formed and sandwich the double barrier structure. As a result, the structure of a resonance tunneling diode, which utilizes the resonance tunneling effect, is provided. Adding a third electrode to the above structure provides a hot electron transistor. In the quantization functional devices having the above-described configuration, the satisfactory resonance effect is obtained due to a high crystallinity of the quantum well, a high potential barrier brought by the high quality silicon oxide films used as the tunneling barriers and a smooth interface between the quantum well and the tunneling barriers.
