Abstract

The invention discloses a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer;the first substrate is provided with a plurality of scanning lines and a plurality of data lines, wherein the scanning lines and the data lines are crossed, a plurality of pixel units are defined, each of the multiple pixel units includes a common electrode, a pixel electrode and a black matrix replacement electrode, and the black matrix replacement electrodes are arranged above the data lines toshield the date lines and are insulated from the data lines; the second substrate and the first substrate are arranged in pairs, a black matrix is arranged on the second substrate and corresponds to aregion between any two adjacent pixel units of the multiple pixel units; and the liquid crystal layer is arranged between the first substrate and the second substrate. By applying a composite structure with the black matrix replacement electrodes and the black matrix at the data line routing positions, the effective aperture ratio and a color mixing light leakage control function can be realized,and the contrast can be significantly improved.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has been widely used in mobile phones, TVs, personal digital assistants, digital cameras, notebook computers, etc. Consumer electronics have become the mainstream of display devices. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small currents in the two glass substrates. The light is refracted to create the picture. [0003] In the early NonCOA (color filter layer set on the color filter substrate) technology, please refer to figure 1 , including a lower substrate 110 and an upper substrate 120, the lower substrate 110 is provided with a common electrode 111, a first insulating layer 112, a data line 113, a second insul...
