Problems solved by technology

Therefore, the conventional LCD must change the process line before and after forming the transparent electrode to manufacture the panel, and the display quality of the panel is lowered due to the instability of the substrate due to the change of the process line

Embodiment Construction

[0029] Throughout the specification, the same reference numerals refer to the same elements in the drawings. It will be understood that when an element is referred to as being "electrically coupled" to another element, it can be electrically coupled to the other element directly or through intervening elements.

[0030] refer to figure 1 , the liquid crystal display 1000 includes a liquid crystal panel 100 (hereinafter also referred to as a “panel”), an X electrode driver 200 and a Y electrode driver 300 .

[0031] The panel 100 includes a plurality of first transparent electrodes X[1], X[2], ..., X[n] arranged in rows, and a plurality of second transparent electrodes Y[1], Y[2], ..., Y[m], and a plurality of first transparent electrodes X[1], X[2], ..., X[n] and a plurality of first transparent electrodes Pixels defined by two transparent electrodes Y[1], Y[2], ..., Y[m]. A pixel 150 (marked by “P” in the figure) may be formed between one of the first transparent electrode...

Abstract

The invention provides a liquid crystal display and its manufacturing method. The liquid crystal display includes a first substrate. A color filter covers the first substrate and includes black matrices and color photoresists. Photo spacers upwardly protrude from the black matrices. The photo spacers are formed using a photolithography process so that the spacers are not formed in color photoresist regions. First transparent electrodes cover the color filter on regions other than regions where the photo spacers are formed aned extend in a first direction. A second substrate faces the first substrate. Second transparent electrodes cover the second substrate, are between the second substrate and the first transparent electrodes and extend in a second direction crossing the first direction.

Description

technical field [0001] The present invention relates to a liquid crystal display and a method of manufacturing the same, and more particularly, to a liquid crystal display having a structure that prevents degradation of display quality due to light leakage. Background technique [0002] As a type of flat panel display, a liquid crystal display (LCD) applies a varying voltage to a liquid crystal layer having optical properties intermediate between conventional liquids and solid crystals, thereby causing changes in the optical properties. Since the LCD has lower power consumption than a conventional cathode ray tube (CRT), is small in size, can be large-sized, and fine-pitched, the LCD has a wide range of applications. [0003] LCDs are classified into active matrix LCDs using switching devices and twisted nematic (TN, twisted nematic) liquids, and passive matrix LCDs using super twisted nematic (STN) liquids. [0004] Active-matrix LCDs use thin-film transistors (TFTs) as sw...
