Abstract

The invention discloses a high-penetrability liquid crystal display panel and a preparation method. The high-penetrability liquid crystal display panel comprises a glass substrate, a first buffer layer, a shading layer, a barrier layer, a second buffer layer, an active layer, a gate insulating layer, a gate metal layer, a source-drain metal layer and a passivation layer, the shading layer is formed on the first buffer layer, and the critical dimension of the shading layer is smaller than that of the first buffer layer; the first buffer layer, the second buffer layer and the gate insulating layer are all insulating films with high penetrability. According to the embodiment of the invention, a laminated structure formed by the high-penetrability insulating film and a barrier metal ion film is arranged at the bottom of the active layer, and the buffer layer in an opening region is arranged to be the high-penetrability insulating film, so that the manufacturing cost of the liquid crystal display panel is reduced while the transmittance of the liquid crystal display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a high-transmittance liquid crystal display panel and a preparation method thereof. Background technique [0002] In recent years, the thin film transistor liquid crystal display (Thin Film Transistor Liquid Display, TFT-LCD) has gradually been developed towards projects such as power saving, high definition and improvement of color reproducibility. Among them, improving the penetration performance to increase the brightness of TFT-LCD and reduce power consumption is a difficult problem that every panel factory is trying to overcome. The penetration of the TFT-LCD panel refers to the ratio of the light intensity before and after the backlight passes through the TFT-LCD panel. Usually, the light transmittance of TFT-LCD is only 3-10%, that is to say, more than 90% of the light cannot be utilized. For TFT, in addition to metal wiring, the transmission rate is also grea...
