A method for producing a glass article is provided. The method for producing a glass article, the method including preparing a glass to be processed, the glass comprising a glass bulk and a low-refractive surface layer disposed on the glass bulk, and etching away the low-refractive surface layer to form an etched glass, wherein the etching away the low-refractive surface layer comprises: cleaning the low-refractive surface layer with an acid solution; and cleaning the low-refractive surface layer with a base solution after the cleaning it with the acid solution.

A liquid crystal display device includes a first substrate and a second substrate facing and spaced apart from each other, a gate line and a data line on the first substrate, the gate line and the data line crossing each other to define red, green, blue and white sub-pixel regions, a thin film transistor connected to the gate line and the data line, a color filter layer consisting of red, green and blue color filters on the second substrate, the red, green and blue color filters corresponding to the red, green and blue sub-pixel regions, respectively, and a liquid crystal layer between the first substrate and the second substrate.

Liquid crystal display device and method of driving the same

Provided is a liquid crystal panel that limits a viewing angle. The liquid crystal panel includes a plurality of color pixels and a plurality of interference sub-pixels. Each of the color pixels includes red (R), green (G) and blue (B) sub-pixels. The interference sub-pixels are included in each of the color pixels and disposed on the same plane as the color pixels to control light that penetrates the liquid crystal panel and travels in side directions of the liquid crystal panel, except the front direction thereof. The viewing angle can be controlled by the interference sub-pixels. Since the interference sub-pixels and the color sub-pixels are disposed on the same plane, the thickness and weight of the liquid crystal panel do not increase. Further, it is possible to prevent the decrease of the light quantity and the degradation of the brightness.

Liquid crystal panel capable of controlling viewing angle and liquid crystal display device with the same

A liquid crystal display for automatically adjusting brightness of interference image displayed at ECB sub pixels of quad type cells of a liquid crystal display panel in accordance with brightness of a background screen is disclosed. The liquid crystal display includes first to n-th look-up tables each holding a mapping of one first to n-th mappings of ECB brightness data to cell location information for the quad cells of the liquid crystal display panel; an image processor that calculates a brightness data distribution of an image; and a viewing angle controller that selects one of the first to the n-th look-up tables depending on the calculated brightness data distribution.

Liquid crystal display and driving method thereof

A display device includes a plurality of pixel cells divided into at least a first pixel cell group and a second pixel cell group; a first data line electrically connected to the pixel cells in the first pixel cell group, and a second data line electrically connected to the pixel cells in the second pixel cell group; and a gate driver driving at least one of the pixel cells in the first pixel cell group concurrently with at least one of the pixel cells in the second pixel cell group.
