  • Patent number: 8633559
    Abstract: A solid-state imaging device includes light-sensing sections serving as pixels, and waveguides each including a core layer and a cladding layer, the waveguides each being disposed at a position corresponding to one of the light-sensing sections. A cross-sectional structure of the waveguide taken in the horizontal direction of an imaging plane is different from a cross-sectional structure of the waveguide taken in the vertical direction of the imaging plane.

  • Patent number: 7345726
    Abstract: Exemplary embodiments provide a liquid crystal display capable of effectively reducing or preventing the alignment disorder of liquid crystal caused by an active element for switching a pixel, capable of achieving uniform and wide viewing angle display, and preferably capable of high quality color display. The liquid crystal display according to exemplary embodiments of the present invention includes an element substrate having a plurality of pixels, each pixel mainly including a pixel electrode and a TFD element; an opposite substrate opposing the element substrate; and a liquid crystal layer between both substrates. The liquid crystal layer includes liquid crystal with negative dielectric anisotropy, the initial alignment of molecules of the liquid crystal being vertical. A dielectric projection is provided on the inner side of the element substrate or the opposite substrate, the dielectric projection being located in the same position as the TFD element in plan view.
