本发明涉及液晶显示技术领域，特别涉及一种彩膜基板及液晶显示装置。
背景技术
液晶显示装置(Liquid Crystal Display，LCD)具有轻薄、功耗小、数字化等优点，目前在市场上越来越受到广泛应用。由于液晶自身不发光，也无法依赖自然光采光，因此必须采用背光源以获得稳定、清晰的显示。一般来说，背光源的电能来源于外接的电池，电池的储电量有限需要经常充电，给使用者带来不便。在现有显示技术中，光从彩膜中穿过基板时，其中黑矩阵区域完全不透光，如果背光源发出来的光为100％，经过液晶面板各层结构后，光的整体的透过率仅为3％～6％。由于液晶面板各层整体的透过率偏低，导致了现有液晶显示装置透光度较差，或者为了保持高透光度，需要给面板施加较高电压，因此上述液晶显示装置功耗大，续航能力较差，应用范围受限制。
