六、 [0001] [0002] [0003] 100年.12月15日核正_頁 發明說明： 【發明所屬之技術領域】 本發明涉及一種廣視角液晶顯示器。 【先前技術】 近年來，具有輕薄、輕巧、低耗電量等優點之液晶顯示 器被廣泛地應躲個人電腦、機電話、電視攝影機 、測量儀器等顯示器上，尤其係具有高畫f、空間利用 效率高、低消耗功率、無輕射等優越特性之薄膜電晶體 液晶顯示器（Thin Film Transist〇r Uquid Crys一 tal Display，TFT LCD)已逐漸成為市場之主流。 TFT LCD係用來控制每一個晝素光通過量之組件，其影像 之產生係讓面板之每一個獨立畫素都能產生想要之色彩 。為了達到這個目的，多個冷陰極燈管必須被用來作為 顯不之貪光源’為了要讓光通過每一個畫素，面板必 須被分割且製造成一個個小門或開關來讓光通過。液晶 顯示器則係使用液晶組件來調變光之屏幕，液晶可以改 變其分子結構’因此可以讓不同程度之光量通過其本身（ 亦可完全阻斷光線）。如第一圖所示，係一種先前技術之 液晶顯示器之平面示意圖。該液晶顯示器1 00 —般包括第 一基板101、第二基板102和夹於二者之間之液晶層107 。該第一基板101與該第二基板1〇2相對設置。該第一基 板101之内表面依次設置一第一透明電極層103與一第一 配向膜105，該第一基板1〇1之外表面設置一第一偏光片 110。該第二基板102之内表面依次設置一彩色濾光片 108、一第二透明電極層1〇4及一第二配向膜1〇6 ’該第 094142523 表單编號A0101 1003464377-0 1363208 100年12月15日修正替換頁 二基板102之外表面設置一第二偏光片111。其中，第一 偏光片110、第二偏光片111、彩色濾光片108、第一配 向膜105及第二配向膜106可決定光通量之最大值與顏色 之產生。當施以一個電壓給配向層，則產生一個電場， 使配向層介面之液晶分子朝某一個方向排列。每一個晝 素都由紅、綠、藍三個子畫素所組成，就如同映像管一 樣。 [0004] 目前最普遍之液晶模式為扭轉向列液晶（TFT-Twisted Nematic，TFT-TN)，其運作原理為電晶體對子畫素施加 零伏特電壓。液晶以及他們控制通過之偏光於兩塊基板 中水平旋轉9¾度。因為第二偏光片111之偏光軸相對於第 一偏光片110之偏光軸偏移90度，所以光線可以通過，如 果紅、綠、藍之子畫素可以充分被照亮，他們將會混合 而於畫面上產生一個白點；惟，如果施加電壓於氧化銦 錫膜（ITO)，則會形成一垂直電場，其將會摧毁液晶之螺 旋結構，液晶分子會試圖將其自身排列成與電場相同之 方向，那樣表示液晶分子最後會與第二偏光片111垂直， 於這個狀態下，偏向入射光線通不過整個子晝素，子晝 素之白點變成了黑點，整個晝面就會呈現黑色。 [0005] 以傳統之陰極射線管（CRT)顯示器與TFT-TN比較， TFT-TN存在視角較小這一問題。當從某個角度觀看TFT-LCD時，將發現顯示器之輝度急劇下降及嚴重色偏現象。 TFT-TN通常只有90度之視角，也就是左右兩邊各45度， 因此，改善視角一直係LCD產業努力之方向。 【發明内容】

December 15th, the present invention is directed to: [Technical Field] The present invention relates to a wide viewing angle liquid crystal display. [Prior Art] In recent years, liquid crystal displays with advantages such as lightness, lightness, low power consumption, etc. have been widely used to hide personal computers, telephones, television cameras, measuring instruments, etc., especially with high-definition f, space utilization. Thin Film Transist〇r Uquid Crys-tal Display (TFT LCD) with high efficiency, low power consumption and no light-emitting characteristics has gradually become the mainstream of the market. The TFT LCD is used to control the components of each element's light throughput. The image is generated so that each individual pixel of the panel produces the desired color. In order to achieve this, a plurality of cold cathode lamps must be used as a source of light. In order for light to pass through each pixel, the panels must be segmented and fabricated into small doors or switches to allow light to pass. Liquid crystal displays use liquid crystal components to modulate the light screen, and liquid crystals can change their molecular structure. This allows different levels of light to pass through itself (and also completely blocks light). As shown in the first figure, it is a schematic plan view of a prior art liquid crystal display. The liquid crystal display 100 generally includes a first substrate 101, a second substrate 102, and a liquid crystal layer 107 sandwiched therebetween. The first substrate 101 is disposed opposite to the second substrate 1〇2. A first transparent electrode layer 103 and a first alignment film 105 are disposed on the inner surface of the first substrate 101. A first polarizer 110 is disposed on the outer surface of the first substrate 101. The inner surface of the second substrate 102 is sequentially provided with a color filter 108, a second transparent electrode layer 1〇4 and a second alignment film 1〇6'. The 094142523 form number A0101 1003464377-0 1363208 100 years 12 On the 15th of the month, a second polarizer 111 is disposed on the outer surface of the replacement substrate 2 substrate 102. The first polarizer 110, the second polarizer 111, the color filter 108, the first alignment film 105, and the second alignment film 106 determine the maximum value of the luminous flux and the generation of the color. When a voltage is applied to the alignment layer, an electric field is generated to align the liquid crystal molecules of the alignment layer interface in a certain direction. Each element consists of three sub-pixels of red, green and blue, just like a picture tube. [0004] The most common liquid crystal mode at present is a TFT-Twisted Nematic (TFT-TN), which operates on the principle that a transistor applies a zero volt to a sub-pixel. The liquid crystals and their controlled polarization are rotated 93⁄4 degrees horizontally in the two substrates. Since the polarization axis of the second polarizer 111 is offset by 90 degrees with respect to the polarization axis of the first polarizer 110, the light can pass, and if the red, green, and blue sub-pixels can be fully illuminated, they will be mixed. A white point is produced on the screen; however, if a voltage is applied to the indium tin oxide film (ITO), a vertical electric field is formed which will destroy the helical structure of the liquid crystal, and the liquid crystal molecules will attempt to align themselves to the same electric field. The direction, that is, the liquid crystal molecules will eventually be perpendicular to the second polarizer 111. In this state, the incident light will not pass through the entire sub-small element, and the white point of the sub-small will become a black dot, and the entire surface will appear black. [0005] A conventional cathode ray tube (CRT) display has a smaller viewing angle than a TFT-TN. When viewing the TFT-LCD from a certain angle, it will be found that the brightness of the display drops sharply and the color shift phenomenon is severe. TFT-TN usually only has a viewing angle of 90 degrees, that is, 45 degrees on both sides. Therefore, improving the viewing angle has always been the direction of the LCD industry.

December 15th Amendment Replacement Page In view of this, A wide viewing angle liquid crystal display is really necessary. A wide viewing angle liquid crystal display includes a first substrate and a second substrate, the first substrate is disposed opposite to the second substrate; a liquid crystal layer is sandwiched between the first substrate and the second substrate; a surface of the first substrate remote from the liquid crystal layer is formed with a first lens array by using a thick film photoresist, and a surface of the second substrate remote from the liquid crystal layer is formed with a second lens array by using a thick film photoresist, the first lens The array includes a plurality of lenses directly formed on a surface of the first substrate, the second lens array including a plurality of lenses directly formed on a surface of the second substrate, each lens of the first lens array and each lens of the second lens array Corresponding to a thin film transistor halogen of the wide viewing angle liquid crystal display. When light is vertically incident on the first substrate by a light source, the light is concentrated by a plurality of lenses of the first lens array, passes through the liquid crystal layer, is incident on the second substrate, and is diverged by the plurality of lenses of the second lens array. Compared with the prior art, the wide viewing angle liquid crystal display has a first lens array and a second lens array respectively formed on the first substrate and the second substrate, and the first lens array and the second lens array both comprise a plurality of lenses. . Therefore, when the light is incident substantially perpendicularly to the first substrate by the surface light source, the light is incident from the first lens array of the first substrate through the liquid crystal layer to the second lens array of the second substrate, and then the light is applied by the plurality of lenses of the second lens array. Divergence. Therefore, the viewing angle of the liquid crystal display can be improved. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Please refer to the second figure, which is a perspective view of the liquid crystal display of the present invention. The liquid crystal display 200 mainly includes a first substrate 201, a second substrate, a form number A0101, a sixth page, a total of 18 pages, a 1003464377-0 136, a 3208 ldo year, a December 15th revision replacement page 202, and a liquid crystal layer 207.

The inner surface 2010 of the first substrate 201 is sequentially provided with a first transparent electrode layer 203 and a first alignment film 205. The inner surface 2020 of the second substrate 202 is sequentially provided with a color filter 208, a second transparent electrode layer 204 and a second alignment film 206. A first convex lens array 2011 is formed on the outer surface of the first substrate 201 by using a thick film photoresist. A first polarizer 211 is disposed on the outer surface of the first convex lens array 2011, and a thick film light is used on the outer surface of the second substrate 202. The resist forms a second convex lens array 2021, and a second polarizer 212 is disposed on the outer surface of the second convex lens array 2 021. The first convex lens array 2011 includes a plurality of micro convex lenses 2012 having a focal point Fj and a focal length of ^; the second convex lens array 2021 includes a plurality of micro convex lenses 2022, and the focal point of the convex lens 2022 is ? 2, the focal length is %. The convex lenses 201 2 and 2022 of the first convex lens array 2011 and the second convex lens array 2021 have a radius ranging from 200 μm to 400 μm. Each of the micro convex lenses 2012 and the second convex lens arrays 2022 of the first convex lens array 2011 corresponds to a thin film transistor. The focal point Fi of the convex lens 2012 of the first convex lens array 2011 and the focal point F2 of the convex lens 2022 of the second convex lens array 2021 are both located in the liquid crystal layer 207, and the focal point F2 of the convex lens 2022 of the second convex lens array 2021 is located in the first convex lens array 2011.

On December 15th, when the first convex substrate 1 〇 11 of the first substrate 201 is replaced The light is condensed by the plurality of micro convex lenses 2012 on the convex lens 2〇12 at the focus of the liquid crystal layer 2〇7. The light continues to propagate in the liquid crystal layer 2〇7 in the original direction to the second convex lens array of the second substrate 202. 2〇21, since the focal length of the convex lens 2022 of the second convex lens array 2021 is within one focal length of the L· convex lens 2012 of the first convex lens array 2011, the light is emitted in a divergent state via the plurality of micro convex lenses 2022. The exit angle is much larger than the angle at which the light is incident on the first substrate 201, so that the human eye can see the image displayed by the display 20 from a larger angle, i.e., the viewing angle of the liquid crystal display 2 is improved.

The convex lens 4012 and the concave lens 4022 of the first convex lens array 4011 and the second concave lens array 4021 have a radius ranging from 200 micrometers to 400 micrometers. Each of the micro convex lenses 4012 of the first convex lens array 4011 and each of the second concave lens arrays 4021 corresponds to a thin film transistor pixel - the focal point F of the convex lens 4012 of the first convex lens array 4011 is standing on the liquid crystal layer In 407, the focal point f2 of the concave lens 4022 of the second concave lens array 4021 can be set at any position.

The second concave lens array 4021 that is incident on the second substrate 402 is propagated in the liquid crystal layer 407, and the light is emitted in a diverging state via the plurality of micro concave lenses 4022. The exit angle is much larger than the angle at which the light is incident on the first substrate 401, so that the human eye can see the image displayed by the display 400 from a larger angle, that is, the viewing angle of the liquid crystal display 400 is improved. [0016] The liquid crystal display 400 shown in FIG. 4, wherein the focus of the convex lens 4012 of the first convex lens array 4011 of the first substrate 401 and the concave lens 4022 of the second concave lens array 4021 of the second substrate 402 are both designed on the second substrate 402. The focus of the concave lens 4022 of the second concave lens array 4021 of the second substrate 402 is designed to be one of the focal lengths of the convex lens 4012 of the first convex lens array 4011 of the first substrate 401. [0017] Please refer to the sixth figure, the light is passed through the liquid crystal display shown in the fourth figure. 094142523 Form No. A0101 Page 9/18 pages 1003464377-0 1363208 December 15th, the nuclear replacement page is another Schematic diagram of the route of communication. When the light is incident substantially perpendicularly on the first convex lens array 4011 of the first substrate 401 by the surface light source, the light is concentrated by the plurality of micro convex lenses 4012 on the second concave lens array 4021 of the second substrate 402, and the light passes through the plurality of concave lens arrays 4021. The minute concave lens 4022 is emitted in a divergent state. The exit angle is much larger than the angle at which the light is incident on the first substrate 401, so that the human eye can see the image displayed by the display 400 from a larger angle, that is, the viewing angle of the liquid crystal display 400 is improved. [0018] Compared with the prior art, the wide viewing angle liquid crystal display has a first lens array and a second lens array respectively formed on the first substrate and the second substrate, and the first lens array and the second lens array are respectively Includes multiple lenses. Therefore, when the light is incident substantially perpendicularly to the first substrate by the surface light source, the light is incident from the first lens array of the first substrate through the liquid crystal layer to the second lens array of the second substrate, and then the light is applied by the plurality of lenses of the second lens array. Divergence. Therefore, the viewing angle of the liquid crystal display can be improved.
