【背景技术】
液晶是介于液态与结晶态之间的一种物质状态。它除了兼有液体和晶体的某些性质（如流动性、各向异性等）外，还有其独特的性质。对液晶的研究现已发展成为一个引人注目的学科。
液晶材料主要是脂肪族、芳香族、硬脂酸等有机物。液晶包括正性液晶和负性液晶，液晶介电各向异性是决定液晶分子在电场中行为的主要参数，若用 、 分别表示液晶平行、垂直于分子取向的介电常数，各向异性可以用 = - 表示。 >0称为正性液晶，反之称为负性液晶。外电场作用下正性液晶分子沿场方向排列，而负性液晶分子垂直场方向排列。由于正性液晶和配套材料技术的成熟性和材料本身的稳定性能，在液晶显示领域使用正性液晶占绝大多数。但由于正性液晶的平行介电常数较大，使得液晶分子与液晶面板的倾斜角较大，液晶显示器的透过率不高。

【附图说明】
图1是本发明实施例的液晶面板的结构示意图；
图2是本发明第一实施例的像素结构示意图；
图3是本发明第二实施例的像素结构示意图；
图4是本发明第三实施例的像素结构示意图；
图5是本发明第四实施例的像素结构示意图。
【具体实施方式】
请参阅图1，图1是本发明实施例的液晶面板的结构示意图。如图1所示，液晶面板10包括：第一基板11、第二基板12、液晶层13以及电极结构14。第二基板12与第一基板11对向设置。液晶层13夹持于第一基板11和第二基板12上，且包括多个液晶分子。电极结构14设置于第一基板11和第二基板12中的至少一个上，且通过电压控制在液晶层13产生电场，以使得液晶分子在电场作用下进行偏转。
在本发明实施例中，液晶分子包括正性液晶分子和负性液晶分子。由于负性液晶分子的垂直介电常数较大，使得液晶分子与基板的倾斜角更小，也就是更加水平于基板进行面内的旋转，如此制得的液晶面板的透过率更高。第一基板11和第二基板12划分成多个像素区域，每个像素区域进一步划分成至少两个子像素区域，同一像素区域的不同子像素区域所对应的液晶分子的初始取向不同或者电极结构14不同。其中，电极结构14包括像素电极和公共电极，对于TN型液晶显示器，二者分别设置在第一基板和第二基板上，而对于IPS型液晶显示器，二者均设置在同一基板上。电极结构14不同可以是像素电极或公共电极的设置方向不同。根据液晶分子组合方式以及电极结构的不同形成不同的像素结构，具体地如图2-5所示。
图2是本发明第一实施例的像素结构示意图。如图2所示，像素结构20分成第一子像素区域21和第二子像素区域22。第一子像素区域21和第二子像素区域22之前设置有隔墙23。正性液晶分子24和负性液晶分子25由隔墙23分隔成分别设置于同一像素区域的不同子像素区域。如向第一子像素区域21注入正性液晶分子24，向第二子像素区域22注入负性液晶分子25。当然在本发明的其他实施例中，也可以是向第一子像素区域21注入负性液晶分子25，向第二子像素区域22注入正性液晶分子24。正性液晶分子24的初始取向不同于负性液晶分子25的初始取向。正性液晶分子24和负性液晶分子25的不同初始取向可以使用光配向技术实现。电极结构包括像素电极26和公共电极27，正性液晶分子24和负性液晶分子25设置在像素电极26和公共电极27之间。同一像素区域的不同子像素区域的电极结构相同。如第一子像素区域21和第二子像素区域22的像素电极26和公共电极27都为纵向设置，当然也可以都设置成横向，在此不作限制。工作时，同一像素区域的不同子像素区域的电极结构分开进行电压控制，实现不同子像素区域的显示。由于负性液晶分子的垂直介电常数较大，使得液晶分子与基板的倾斜角更小，也就是更加水平于基板进行面内的旋转，如此制得的液晶面板的透过率更高。
图3是本发明第二实施例的像素结构示意图。如图3所示，像素结构30分成第一子像素区域31和第二子像素区域32。第一子像素区域31和第二子像素区域32之间没有设置隔墙。正性液晶分子和负性液晶分子以混合方式设置，形成混合液晶33。同一像素区域的同一子像素区域内的正性液晶分子和负性液晶分子的初始取向彼此相同，并且同一像素区域的不同子像素区域内的正性液晶分子和负性液晶分子的初始取向彼此不同。同一像素区域的不同子像素区域内的正性液晶分子和负性液晶分子的不同初始取向可以使用光配向技术实现。电极结构包括像素电极34和公共电极35，正性液晶分子和负性液晶分子设置在像素电极34和公共电极35之间。同一像素区域的不同子像素区域的电极结构相同。如第一子像素区域31和第二子像素区域32的像素电极34和公共电极35都为纵向设置，当然也可以都设置成横向，在此不作限制。工作时，同一像素区域的不同子像素区域的电极结构可以分开进行电压控制，或者也可以共同进行电压控制，以实现不同子像素区域的显示。由于负性液晶分子的垂直介电常数较大，从而提高了液晶混合物的垂直介电常数。而较大的垂直介电常数会使得液晶分子与基板的倾斜角更小，也就是更加水平于基板进行面内的旋转，如此制得的液晶面板的透过率更高。实验表明正负性混合液晶的透过率相比于正性液晶可提高3%~8%。
图4是本发明第四实施例的像素结构示意图。如图4所示，像素结构40分成第一子像素区域41和第二子像素区域42。第一子像素区域41和第二子像素区域42之间设置有隔墙43。即正性液晶分子44和负性液晶分子45由隔墙43分隔成分别设置于同一像素区域的不同子像素区域。同一像素区域的不同子像素区域内正性液晶分子44和负性液晶分子45的初始取向相同。电极结构包括像素电极46和公共电极47，正性液晶分子44和负性液晶分子45设置在像素电极46和公共电极47之间。同一像素区域的不同子像素区域的电极结构彼此不同。如第一子像素区域41的像素电极46和公共电极47为横向设置，第二子像素区域42的像素电极46和公共电极47为纵向设置。当然也可以是第一子像素区域41的像素电极46和公共电极47为纵向设置，第二子像素区域42的像素电极46和公共电极47为横向设置，在此不作限制。工作时，同一像素区域的不同子像素区域的电极结构分开进行电压控制，实现不同子像素区域的显示。由于负性液晶分子的垂直介电常数较大，使得液晶分子与基板的倾斜角更小，也就是更加水平于基板进行面内的旋转，如此制得的液晶面板的透过率更高。
图5是本发明第三实施例的像素结构示意图。如图5所示，像素结构50分成第一子像素区域51和第二子像素区域52。第一子像素区域51和第二子像素区域52之间没有设置隔墙。正性液晶分子和负性液晶分子以混合方式设置，形成混合液晶53。同一像素区域的不同子像素区域内正性液晶分子和负性液晶分子的初始取向相同。电极结构包括像素电极54和公共电极55，正性液晶分子和负性液晶分子设置在像素电极54和公共电极55之间。同一像素区域的不同子像素区域的电极结构彼此不同。如第一子像素区域51的像素电极54和公共电极55为横向设置，而第二子像素区域52的像素电极54和公共电极55为纵向设置。当然也可以是第一子像素区域51的像素电极54和公共电极55为纵向设置，而第二子像素区域52的像素电极54和公共电极55为横向设置，在此不作限制。工作时，同一像素区域的不同子像素区域的电极结构可以分开进行电压控制，或者也可以共同进行电压控制，实现不同子像素区域的显示。由于负性液晶分子的垂直介电常数较大，从而提高了液晶混合物的垂直介电常数。而较大的垂直介电常数会使得液晶分子与基板的倾斜角更小，也就是更加水平于基板进行面内的旋转，如此制得的液晶面板的透过率更高。实验表明正负性混合液晶的透过率相比于正性液晶可提高3%~8%。
本发明还提供一种液晶显示器，包括上述的液晶面板，通过在液晶层中同时使用正性液晶分子和负性液晶分子，并与不同的电极结构搭配组成不同的像素结构。由于负性液晶分子的垂直介电常数较大，从而提高了液晶混合物的垂直介电常数。而较大的垂直介电常数会使得液晶分子与基板的倾斜角更小，也就是更加水平于基板进行面内的旋转，如此制得的液晶面板的透过率更高。实验表明正负性混合液晶的透过率相比于正性液晶可提高3%~8%。
综上所述，本发明的液晶面板包括：第一基板；第二基板，与第一基板对向设置；液晶层，夹持于第一基板和第二基板上，且包括多个液晶分子；电极结构，设置于第一基板和第二基板中的至少一个上，且通过电压控制在液晶层产生电场，以使得液晶分子在电场作用下进行偏转；其中，液晶分子包括正性液晶分子和负性液晶分子，第一基板和第二基板划分成多个像素区域，每个像素区域进一步划分成至少两个子像素区域，同一像素区域的不同子像素区域所对应的液晶分子的初始取向不同或者电极结构不同，能够提高液晶面板的透过率。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
