    • An in-plane switching mode liquid crystal display device is provided that prevents light leakages and improves contrast ratio. The in-plane switching mode liquid crystal display device includes first and second substrate, gate and data lines that perpendicularly cross each other on the first substrate to define a pixel region, a thin film transistor at a crossing of the gate and data lines, a pixel electrode and a common electrode alternately formed in the pixel region and spaced apart from each other by a predetermined distance, an alignment layer on an entire surface of the substrate, wherein, at least one of the gate line, the data line, the pixel electrode, and the common electrode has a stepped portion with a step difference of about 0.1 μm or greater, the alignment layer is primarily aligned, and at least a portion of the primarily-aligned alignment layer around the stepped portion is secondarily aligned, and a liquid crystal layer between the first and second substrates.
    • 提供一种面内切换模式液晶显示装置,其防止光泄漏并提高对比度。 面内切换模式液晶显示装置包括第一和第二基板,在第一基板上彼此垂直交叉以限定像素区域的栅极和数据线,在栅极和数据线的交叉处的薄膜晶体管, 像素电极和公共电极,交替地形成在所述像素区域中并且彼此间隔开预定距离;在所述基板的整个表面上的取向层,其中,所述栅极线,所述数据线,所述像素中的至少一个 电极,公共电极具有阶梯差为约0.1μm以上的台阶部,取向层主要对准,并且台阶部周围的主要取向取向层的至少一部分二次对准,并且 在第一和第二基板之间的液晶层。
