201024838 九、發明說明: 【發明所屬之技術領域】 本發明是有關於一種彩色濾光片基板及其應用’且特 別是有關於可增加在後續組裝時框膠所照射到之光強度的 彩色濾光片基板及其在液晶顯示裝置上的應用。 【先前技術】 隨著資訊、通信產業不斷地推陳出新’帶動了液晶顯 示器(Liquid Crystal Display ; LCD)市場的蓬勃發展。液晶 顯示器具有高晝質、體積小、重量輕、低驅動電壓、與低 消耗功率等優點,因此被廣泛應用於個人數位助理 (Personal Digital Assistant; PDA)、行動電話、攝錄放影機、 筆記型電腦、桌上型顯示器、車用顯示器、及投影電視等 消費性通訊或電子產品。加上積體電路(Integrated Circuit ; 1C)產業與液晶顯示器製造技術的突飛猛進,這些消费性通 訊或電子產品亦朝向輕、薄、短、小的趨勢發展。尤其是 在電腦產品方面,除了高性能、高速度之桌上型電腦外’ 攜帶方便的筆記型電腦更是受到極大的注意與重視。 一般液晶顯示器之主體為液晶單元,主要是由兩片透 明基板以及被封於基板之間的液晶所構成。目前液晶顯示 器是以薄膜電晶艘(Thin Film Transistor ; TFT)液晶顯示器 為主,而一般薄膜電晶體液晶顯示器之製作可大致區分為 薄膜電晶體陣列(TFT Array)製程、彩色濾光片(Color Filter) 製程、液晶顯示單元組裝(LC Cell Assembly)製程、液晶顯 201024838 示模組(Liquid Crystal Module ; LCM)製程。 在製作薄膜電晶體液晶顯示器時,薄膜電晶體陣列製 程係用以製作薄膜電晶體基板,其上薄膜電晶體陣列與畫 素電極陣列,彼此呈相對應關係。而彩色濾光片製程是由 不同顏色的彩色濾光單元所組成之彩色濾光陣列與包圍於 其周圍之黑色矩陣(Black Matrix)所構成。黑色矩陣主要用 來遮擋薄膜電晶體、氧化銦錫(ITO)上的佈線以及顯示區域 靠近電極的部分。 液晶顯示單元的組裝製程,則是將薄膜電晶體基板與 彩色濾光片基板加以平行組裝,由二者間之間隙構成液晶 槽。再於液晶槽中注入液晶材料,並將液晶槽之注入口密 封’以完成液晶顯示單元之製作。 傳統液晶注入製程非常繁瑣,因此藉由滴下式注入 (One Drop Fill ; ODF)製程,可有效的簡化生產流程。當使 用ODF製程時,一般採用紫外線硬化型框膠,來確保製程 良率。然而’當實際生產時’若紫外線硬化型框膠照光不 足的情況下,液晶顯示面板的液晶常常受到框膠污染,反 而降低生產的良率以及造成生產的瓶頸。再者,當紫外光 (UV Light)由彩色濾光片基板來照射至框膠時,由於紫外光 需通過彩色濾光片基板上的ITO電極,方可照射至框膠, 因而紫外光的部分能量容易被ITO電極所吸收,導致框膠 被照射到的光強度減少15〜20%。 【發明内容】 因此本發明之一方面係在於提供一種彩色濾光片基板 201024838 及其應用,藉以當進行液晶顯示面板的組裝時,可增加框 膠所照射到的光強度,因而可減少光源所使用的照射強度 和照射時間。 本發明之又一方面係在於提供一種液晶顯示面板的組 裝方法,藉以減少彩色濾光片基板的透光導電層對於光線 的吸收,而增加框膠所照射到的光強度。 根據本發明之實施例,本發明之彩色濾光片基板至少 包含有透光基板、遮光層、彩色濾光層及透光導電層。遮 ❿ 光層係形成於透光基板上,並具有黑色矩陣(Black Matrix) 結構。彩色濾光層係形成於透光基板上,並設置於黑色矩 陣結構中。透光導電層係形成於遮光層和彩色濾光層上, 其中透光導電層具有圖案化開口,圖案化開口的形成位置 係對應於框膠。 又,根據本發明之實施例,本發明之液晶顯示面板至 ;包含有彩色濾光片基板、薄膜電晶體基板、液晶層及框 膠。彩色壚光片基板設有透光導電層,其中透光導電層具 ® 有圖案化開口,薄膜電晶體基板係相對於彩色濾光片基 板,液晶層係設置於彩色濾光片基板與薄膜電晶體基板之 間’框膠係設置於彩色濾光月基板與薄膜電晶體基板之 間’並形成於液晶層的外圍,其中透光導電層之圖案化開 口形成位置係對應於框膠。 又’根據本發明之實施例,上述液晶顯示面板可應用 於液晶顯示裝置中。 又,根據本發明之實施例’本發明之液晶顯示面板的 組裝方法至少包含··提供彩色濾光片基板,其中彩色遽光 7 201024838 片基板設有透光導電層,且透光導電層具有至少一圓案化 開口;提供薄膜電晶體基板;形成液晶層於彩色濾光片基 板和薄膜電晶體基板之間;藉由框膠來組合彩色渡光片基 板和薄膜電晶體基板,其中透光導電層之圖案化開口的形 成位置係對應於框膠;以及照射光線至框膠,以硬化框膠。 因此,本發明之彩色濾光片基板及其應用可增加框膝 所照射到的光強度,因而可延長照射光源的使用壽命,或 者可減少光源的設置數目。 【實施方式】 為讓本發明之上述和其他目的、特徵、優點與實施例 能更明顯易懂’本說明書將特舉出一系列實施例來加以說 明。但值得注意的是’此些實施例只是用以說明本發明之 實施方式,而非用以限定本發明。 請參照第2圖至第3B圖,第2圖係繪示依照本發明之 第一實施例之液晶顯示裝置的刻面示意圖,第3A圖係繪示 〇 依照本發明之第一實施例之第一基板與電極結構的剖面示 意圖,第3B圖係繪示依照本發明之第一實施例之電極結構 的俯視示意圖。本實施例之液晶顯示裝置(Liquid Crystal Display ;

Description of the Invention: [Technical Field] The present invention relates to a color filter substrate and its application, and in particular to a color filter that can increase the intensity of light that is irradiated by the sealant during subsequent assembly. Light sheet substrate and its application on a liquid crystal display device. [Prior Art] With the continuous development of the information and communication industry, the market for liquid crystal displays (LCD) has flourished. Liquid crystal displays are widely used in personal digital assistants (PDAs), mobile phones, video recorders, and notebooks because of their high quality, small size, light weight, low driving voltage, and low power consumption. Consumer communications or electronic products such as computers, desktop displays, automotive displays, and projection televisions. Coupled with the rapid advancement of the integrated circuit (1C) industry and liquid crystal display manufacturing technology, these consumer communications or electronic products are also moving toward light, thin, short and small trends. Especially in terms of computer products, in addition to high-performance, high-speed desktop computers, portable notebooks have received great attention and attention. Generally, the main body of the liquid crystal display is a liquid crystal cell, and is mainly composed of two transparent substrates and a liquid crystal sealed between the substrates. At present, the liquid crystal display is mainly a thin film transistor (TFT) liquid crystal display, and the general thin film transistor liquid crystal display can be roughly divided into a thin film transistor array (TFT Array) process, a color filter (Color) Filter) Process, liquid crystal display unit assembly (LC Cell Assembly) process, liquid crystal display 201024838 display module (Liquid Crystal Module; LCM) process. In the fabrication of a thin film transistor liquid crystal display, a thin film transistor array process is used to fabricate a thin film transistor substrate, on which a thin film transistor array and a pixel electrode array are associated with each other. The color filter process is composed of a color filter array composed of color filter units of different colors and a black matrix surrounded by the black matrix. The black matrix is mainly used to shield the thin film transistor, the wiring on the indium tin oxide (ITO), and the portion of the display region close to the electrode.

The traditional liquid crystal injection process is very cumbersome, so the production process can be simplified by the One Drop Fill (ODF) process. When using the ODF process, UV-curing frame seals are generally used to ensure process yield. However, in the case of actual production, if the ultraviolet curing type frame glue is insufficiently illuminated, the liquid crystal of the liquid crystal display panel is often contaminated by the frame glue, which in turn reduces the yield of production and causes a bottleneck in production. Furthermore, when the ultraviolet light is irradiated to the sealant by the color filter substrate, the ultraviolet light needs to pass through the ITO electrode on the color filter substrate to be irradiated to the sealant, so that the ultraviolet light portion The energy is easily absorbed by the ITO electrode, causing the light intensity of the sealant to be reduced by 15 to 20%.
