Abstract: According to an aspect, a liquid crystal display device includes a first electrode having a plurality of electrode base portions that extend in a first direction; a plurality of first comb-shaped portions that protrude from each of the plurality of electrode base portions in a second direction; and a plurality of second comb-shaped portions that protrude from each of the plurality of electrode base portions in an opposite direction to the second direction. Front edges of the first comb-shaped portions and the second comb-shaped portions that extend from the adjacent electrode base portions face each other with a gap therebetween, respectively. Transmission ineffective areas are formed at portions between the front edges facing each other, respectively, and not continuously aligned.

Abstract: A liquid crystal display (LCD) panel comprising a signal line, a first dielectric layer, a liquid crystal layer, a pixel electrode, and a thin film transistor (TFT) is provided. The first dielectric layer with a first permittivity ?1 is formed on the signal line and the TFT. An average permittivity of the liquid crystal layer is a second permittivity ?2 greater than the first permittivity ?1. The pixel electrode neighbors with the signal line. The distance between the signal line and a side of the first dielectric layer is a first distance d1, and the distance between a side of the first dielectric layer and a side of the pixel electrode is a second distance d2, wherein the second permittivity ?2, the first permittivity ?1, the first distance d1 and the second distance d2 are conformed to the following inequality: ( 1 ? ? ? 1 ? ? ? 2 × ? 2 ? 1 + 1 ) × ? ? ? 2 < V ? ? th V ? ? d .

Abstract: An LCD having a backlight module is proposed. The backlight module includes an ambient light collector for collecting ambient light; a back plate; a diffuser plate on the back plate; a plurality of optical fibers straightly fixed between the diffuser plate and the back plate and coupled to the ambient light collector. Microstructure is formed on the surface of the optical fibers straightly fixed between the diffuser plate and the back plate, and the microstructure makes light from the optical fibers evenly being emitted. The backlight module utilizes microstructure formed on a surface of optical fibers for evenly distributing light from the surface of the optical fibers. In hence, it effectively guides ambient light into the backlight module via the optical fibers and ensures at the same time that the light is evenly distributed to the backlight module.
