Abstract:
1. A liquid crystal display device comprising: a first substrate; a second substrate over the first substrate; a liquid crystal layer including a liquid crystal material exhibiting a blue phase between the first substrate and the second substrate; a transistor comprising a semiconductor layer over the first substrate; an interlayer film over the transistor wherein the interlayer film has a contact hole exposing a art of the semiconductor layer; a first structure body over the interlayer film, and between the interlayer film and the liquid crystal layer, wherein the first structure body has a rib-shaped cross-section, and wherein a side surface of the first structure body comprises a tapered shape; a second structure body over the interlayer film, and between the interlayer film and the liquid crystal layer, wherein the second structure body has a rib-shaped cross-section, wherein a side surface of the second structure body comprises a tapered shape, and wherein a part of the second structure body is provided between parts of the first structure body; a first electrode layer electrically connected to the semiconductor layer through the contact hole, wherein the first electrode layer covers a top surface and the side surface of the first structure body, wherein the first electrode layer is configured to be applied with a first potential; and a second electrode layer which covers a top surface and the side surface of the second structure body, wherein the second electrode layer is configured to be applied with a second potential, wherein the first electrode layer is elongated from the side surface of the first structure body toward the second structure body on the interlayer film, wherein the second electrode layer is elongated from the side surface of the second structure body toward to the first structure body on the interlayer film, wherein the interlayer film has a curved inner wall surface at the contact hole, and wherein the first structure body has a skirt shape at a bottom of the first structure body.
