The role. Generally, the main structure of the TFT-LCD is composed of an array substrate, a color filter substrate, a polarizing plate, and a backlight. The array substrate and the color filter substrate are packaged in a liquid crystal box to form a liquid crystal cell. The color filter substrate is used to provide color to the display.

Further, the lower edge of the liquid crystal display is prone to color unevenness (ie, the gravity mura effect), which greatly affects the display effect of the image. In addition, the color pixel layer in the color film substrate generally only includes three primary color (red, green, blue) pixel layers, so that the color display of the image is too singular, which limits the visual effect of the image, so that the user's viewing feeling is not high. Summary of the invention
本发明的一个实施例提供彩膜基板， 包括： 基板， 形成在所述基板上的 黑矩阵和彩色像素层， 形成在所述彩色像素层上方的隔垫物， 其中， 所述黑 矩阵、 彩色像素层和隔垫物中至少有一个为中空体结构。  An embodiment of the present invention provides a color filter substrate, including: a substrate, a black matrix and a color pixel layer formed on the substrate, and a spacer formed over the color pixel layer, wherein the black matrix, color At least one of the pixel layer and the spacer is a hollow body structure.
本发明的另一实施例提供显示装置， 包括上述彩膜基板。  Another embodiment of the present invention provides a display device including the above color film substrate.
本发明的又一实施例提供制作彩膜基板的方法， 包括： 在基板上形成实 心黑矩阵和实心彩色像素层； 在完成上述步骤的基板上形成实心隔垫物； 将 所述实心黑矩阵、 实心彩色像素层和实心隔垫物中至少一个制作成中空体结 构。 附图说明 Yet another embodiment of the present invention provides a method of fabricating a color filter substrate, comprising: forming a solid on a substrate a black matrix and a solid color pixel layer; a solid spacer formed on the substrate on which the above steps are performed; at least one of the solid black matrix, the solid color pixel layer and the solid spacer is formed into a hollow body structure. DRAWINGS
为了更清楚地说明本发明实施例的技术方案， 下面将对实施例或现有技 术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图 仅仅涉及本发明的一些实施例， 并非对本发明的限制。  In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments or the prior art description will be briefly described below. Obviously, the drawings in the following description relate only to some of the present invention. The examples are not intended to limit the invention.
图 1为根据本发明第一实施例的彩膜基板结构示意图；  1 is a schematic structural view of a color filter substrate according to a first embodiment of the present invention;
图 2为根据本发明第二实施例的彩膜基板结构示意图； 具体实施方式  2 is a schematic structural view of a color filter substrate according to a second embodiment of the present invention;
本发明要解决的技术问题之一是提供显示装置、彩膜基板及其制作方法， 以克服现有的显示装置自身结构厚重、 色彩单一且易出现重力 mura效应等 缺陷。  One of the technical problems to be solved by the present invention is to provide a display device, a color filter substrate, and a manufacturing method thereof, which overcome the defects of the prior art display device having a heavy structure, a single color, and a gravity mura effect.
下面将结合附图，对本发明实施例中的技术方案进行清楚、完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有做出创造性劳动前提下 所获得的所有其他实施例， 都属于本发明保护的范围。 例如第一实施例  The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. For example, the first embodiment
如图 1所示， 本实施例的彩膜基板包括： 基板 1， 设在基板 1上的黑矩 阵 2和彩色像素层， 该彩色像素层至少包括红色像素层 3、 绿色像素层 4和 蓝色像素层 5。彩色像素层上方设有隔垫物 6;该彩色像素层与隔垫物之间可 设有平坦层 7， 用于平坦该彩色像素层的表面。  As shown in FIG. 1, the color filter substrate of this embodiment includes: a substrate 1, a black matrix 2 and a color pixel layer disposed on the substrate 1, the color pixel layer including at least a red pixel layer 3, a green pixel layer 4, and a blue layer. Pixel layer 5. A spacer 6 is disposed above the color pixel layer; a flat layer 7 may be disposed between the color pixel layer and the spacer for flattening the surface of the color pixel layer.
本实施例中，该彩色像素层包括红色像素层、绿色像素层和蓝色像素层。 根据实际显示图像色彩的需要， 该彩色像素层还可以包括白色像素层、 黄色 像素层或其他色彩的像素层。  In this embodiment, the color pixel layer includes a red pixel layer, a green pixel layer, and a blue pixel layer. The color pixel layer may further include a white pixel layer, a yellow pixel layer, or a pixel layer of other colors depending on the actual display of the color of the image.
该黑矩阵 2、 彩色像素层和隔垫物 6中至少有一个为中空体。 本实施例 中隔垫物 6为中空体。 将隔垫物 6设置成中空体， 可有效减轻彩膜基板的重 量， 进而减轻最终产品的重量， 使得产品更加的轻薄化。 另外， 当显示装置 长期处于高温、 通电的状态下， 液晶很容易在高温和重力的综合作用下发生 下沉现象， 使得液晶面板下边缘出现色不均的现象（即重力 mura效应） ， 影响画面的图像显示， 而将隔垫物设置成中空体结构， 可有效避免液晶面板 在高温环境下发生重力 mura效应， 提高液晶面板的显示图像的品质， 提高 用户体验感。 At least one of the black matrix 2, the color pixel layer, and the spacer 6 is a hollow body. In the present embodiment, the spacer 6 is a hollow body. By arranging the spacer 6 as a hollow body, the weight of the color filter substrate can be effectively reduced, thereby reducing the weight of the final product, and making the product more light and thin. In addition, when the display device is in a state of high temperature and power for a long time, the liquid crystal easily occurs under the combined action of high temperature and gravity. The phenomenon of sinking causes the unevenness of the color at the lower edge of the liquid crystal panel (ie, the effect of gravity mura), affecting the image display of the screen, and setting the spacer to a hollow body structure, which can effectively prevent the liquid crystal panel from generating gravity in a high temperature environment. The mura effect improves the quality of the display image of the liquid crystal panel and improves the user experience.
本发明制作第一实施例中彩膜基板的方法例如包括：  The method for fabricating the color filter substrate in the first embodiment of the present invention includes, for example:
步骤 1 : 在玻璃基板上釆用构图工艺形成黑矩阵。 此构图工艺可采用现 有技术中常规的构图工艺， 例如可包括掩模、 曝光、 刻蚀和清洗等步骤。  Step 1: On the glass substrate, a black matrix is formed by a patterning process.

步骤 2: 在完成上述步骤的基板上采用构图工艺形成彩色像素层。 该彩 色像素层包括红色像素层、 绿色像素层和蓝色像素层。  Step 2: forming a color pixel layer by a patterning process on the substrate on which the above steps are completed. The color pixel layer includes a red pixel layer, a green pixel layer, and a blue pixel layer.
步骤 3: 在彩色像素层上采用构图工艺形成平坦层， 该平坦层用于平坦 彩色像素层的表面。  Step 3: A planarization layer is formed on the color pixel layer using a patterning process for flattening the surface of the color pixel layer.
步骤 4: 在平坦层上涂覆负性光刻胶， 采用构图工艺形成实心结构的隔 垫物。  Step 4: Apply a negative photoresist to the flat layer and form a solid structure spacer using a patterning process.
步骤 5: 在实心隔垫物的结构外涂覆一层正性光刻胶， 经过掩模、 曝光 和控制曝光量， 在正性光刻胶层中形成若干个孔隙， 该孔隙暴露出正性光刻 胶层下方的实心隔垫物的部分外表面， 在该过程中隔垫物的负性光刻胶不被 溶解。  Step 5: Apply a layer of positive photoresist to the structure of the solid spacer. After masking, exposing and controlling the exposure amount, a plurality of pores are formed in the positive photoresist layer, and the pores expose positiveness. A portion of the outer surface of the solid spacer under the photoresist layer, during which the negative photoresist of the spacer is not dissolved.
步骤 6: 使用有机溶剂透过该正性光刻胶层中形成的孔隙， 对正性光刻 胶下方的实心隔垫物的部分的负性光刻进行溶解， 被溶解掉的负性光刻胶随 着有机溶液从孔隙中流出， 即形成中空结构的隔垫物。 该有机溶剂只与负性 光刻胶发生化学反应， 而与正性光刻胶不发生化学反应。 该有机溶剂例如可 选用： 浓度为 0.04%KOH溶液或 2.38%的 TMAH (四曱基氢氧化铵 )溶液， 或具备一定浓度的 Na2CO3溶液。 之后， 可以去除其中形成有孔隙的正性光 刻胶层。 Step 6: using an organic solvent to penetrate the pores formed in the positive photoresist layer, dissolve the negative lithography of the portion of the solid spacer under the positive photoresist, and dissolve the negative lithography The glue flows out of the pores as the organic solution forms a spacer of a hollow structure. The organic solvent only chemically reacts with the negative photoresist, but does not chemically react with the positive photoresist. The organic solvent may, for example, be selected from a solution having a concentration of 0.04% KOH or 2.38% of a TMAH (tetradecyl ammonium hydroxide) solution or a solution having a certain concentration of Na 2 CO 3 . Thereafter, a positive photoresist layer in which voids are formed can be removed.
