200914934 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種液晶顯示裝置，尤指一種適用於彩 色顯示之液晶顯示裝置。 5 【先前技術】 一般而吕，液晶顯示器（Liquid Crystal Display，LCD ) 〇 的色彩呈現方式為利用背光模組所發射出來的白光，在透 過液晶層時改變亮度’再利用彩色濾光片（Color Filter，CF ) 10 來呈現不同的色彩。 圖1與圖2為目前常見彩色濾光片的光透過頻譜圖，其 中圖1為高色彩飽和度低亮度的彩色濾光片，圖2為低色彩 飽和度高亮度的彩色濾光片。根據圖1與圖2可以得知，彩 色渡光片的帶寬過大，於通過單一色光時，容易使其他色 15 雜光通過’因此彩色濾光片的濾光效果常見有色偏現象。 ◎ 舉例來說’圖1中顯示之CF-Red曲線係顯示來自背光模組之 光線經彩色濾光片之紅色濾光片濾光之後的通過光組成， 除了紅光（約625nm〜700nm)可通過之外，其亦使靠近波 長500nm處之綠光通過，因此造成紅色光純度不足而產生色 20 偏。 另一方面，圖3與圖4為目前常見背光模組的光透過頻 譜圖，其中圖3為冷陰極螢光燈型背光模組，圖4為發光二 極體型背光模組。如圖3與圖4所示，各光源之顏色波段中 200914934 包括不少雜光，而這些光源再經過帶寬過寬之彩色瀘、光片 之後，穿透光之色純度並不理想。 常見針對色純度不佳的缺點的改良方式有：在彩色渡 光片中使用高色彩飽和度的色料、更換背光模組中的光源 5 使用的螢光體或者在冷陰極燈管（CCFL)與導光板（LightBACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device suitable for color display. 5 [Prior Art] Generally, the liquid crystal display (LCD) color is expressed by the white light emitted by the backlight module, and the brightness is changed when passing through the liquid crystal layer. Reusing the color filter (Color) Filter, CF ) 10 to render different colors. Fig. 1 and Fig. 2 are light transmission spectrum diagrams of current common color filters, wherein Fig. 1 is a color filter with high color saturation and low brightness, and Fig. 2 is a color filter with low color saturation and high brightness. It can be seen from Fig. 1 and Fig. 2 that the bandwidth of the color passage sheet is too large, and when a single color light is passed, it is easy to pass other color 15 stray light. Therefore, the color filter of the color filter is often colored. ◎ For example, the CF-Red curve shown in Figure 1 shows that the light from the backlight module is filtered by the red filter filtered by the color filter, except for red light (about 625 nm to 700 nm). In addition, it also passes green light near the wavelength of 500 nm, thus causing insufficient red light purity to produce a color shift. On the other hand, FIG. 3 and FIG. 4 are light transmission spectrum diagrams of current common backlight modules, wherein FIG. 3 is a cold cathode fluorescent lamp type backlight module, and FIG. 4 is a light emitting diode type backlight module. As shown in Fig. 3 and Fig. 4, 200914934 includes a lot of stray light in the color band of each light source, and the color purity of the penetrating light is not ideal after the light source is over-width wide. Common improvements to the disadvantages of poor color purity include: the use of high color saturation toners in color drips, the replacement of phosphors used in light source 5 in backlight modules, or in cold cathode lamps (CCFL). With light guide (Light
Guide)之間設置一帶通濾光片（Bandpass Fiiter)。然而， 在使用咼色彩飽和度的色料的方式中，目前可使用的材料 雖能提高色彩飽和度’不過彩色濾光片之帶通寬度仍大， 故色純度亦不理想。此外，當提高色彩飽和度時，整體的 1〇 光透過率也會降低，導致液晶顯示器整體亮度衰減。另一 方面’在更換背光模組的螢光體方式中，雖然改善了色彩 飽和度，不過仍然因為彩色遽光片的帶通寬度過寬而不理 想。 此外，在冷陰極燈管與導光板之間，設置一帶通濾光 15片之方式係利用帶通濾、光片中螢光體材料吸收特定波段的 光，藉此切斷冷陰極燈管發出之白光中不需要的光頻帶， =讓特定波長的光通過。然而，現有的帶_光片吸光效 率有限依然發生色偏現象，造成色純度無法達到設計需 求。 “上所述，解決彩色遽光片的帶通寬度過寬或帶通減 =使白光，純度不理想等習知缺點，以提升液晶顯示器 、色純度，貫為刻不容緩之課題。 【發明内容】 200914934 本發明之一目的係在提供一種液晶顯示裝置，俾使顯 示晝面之色純度增加。 本發明之另一目的係在提供一種液晶顯示裝置，俾使 顯不晝面之色飽和度增加。 5 本發明之液晶顯示裝置包括：一液晶面板、一背光模 組以及至少一帶止濾光膜。背光模組具有一光源，而帶止 濾光膜則配置於液晶面板及背光模組之間，其中，帶止濾 光膜用以過濾光源之一區段波長。 本發明之皮光模組係無限定為何種形式之背光模組， 10 其可為直下型背光模組、側光型背光模組或其他形式之背 光模組’然其較佳係為侧光型背光模組，其可包括一導光 板以及一擴散板，而且導光板係鄰接於光源，擴散板係層 疊於導光板。此外，上述光源之種類型式亦無限定，其較 佳為發光二極體或螢光燈管，其中螢光燈管可為冷陰極螢 15 光燈管（CCFL)或熱陰極螢光燈管（HCFL )，並以發光 二極體為更佳。 本發明之液晶面板之態樣不限，其較佳包括一上基 板、一液晶層以及一陣列基板，其中液晶層配置於上基板 與陣列基板之間。 2〇 本發明之液晶顯示裝置可更包括一彩色濾光片，其可 配置於液晶面板之一侧。然而’上述彩色濾光片之形式亦 無限定，其較佳為包括多數遮光層以及至少一滤光層，其 中遮光層配置於上基板之上，而且遮光層為陣列排列且可 定義多數個次畫素區，濾、光層則配置於次畫素區中。 200914934 此外，本發明之液晶顯示裝置可更包括二偏光片，並 可將液晶面板設置於該些偏光片之間。 本發明之帶止遽光膜態樣不限，然其較佳為一多層膜 堆，而且此多層膜堆的設計可如下式所示：A Bandpass Fiiter is placed between the Guides. However, in the method of using the color saturation of the color saturation, the currently usable material can improve the color saturation. However, the band width of the color filter is still large, so the color purity is not satisfactory. In addition, when the color saturation is increased, the overall light transmittance of the light is also lowered, resulting in a decrease in the overall brightness of the liquid crystal display. On the other hand, in the phosphor mode in which the backlight module is replaced, although the color saturation is improved, it is still unreasonable because the band width of the color chopper sheet is too wide. In addition, between the cold cathode lamp tube and the light guide plate, a band pass filter 15 is arranged by using a band pass filter, and the phosphor material in the light piece absorbs light of a specific wavelength band, thereby cutting off the cold cathode lamp tube. The unwanted optical band in white light, = let light of a specific wavelength pass. However, the existing band-light absorption efficiency is still limited, and the color purity is not achieved, which causes the color purity to fail to meet the design requirements. "The above description solves the problem that the band width of the color grading sheet is too wide or the band pass is reduced = the white light is not ideal, and the purity is not ideal, so as to improve the liquid crystal display and the color purity. 200914934 One object of the present invention is to provide a liquid crystal display device which increases the color purity of the display surface.
