Abstract

The invention discloses a blue-phase liquid crystal display panel, which comprises a first substrate, a second substrate, a blue-phase liquid crystal layer and an auxiliary material layer. The first substrate comprises multiple pixel driving units. Each pixel driving unit comprises a pixel electrode and an opposite electrode so as to provide an electric field. The second substrate is configured opposed to the first substrate. The blue-phase liquid crystal layer is sealed between the first substrate and the second substrate. The blue-phase liquid crystal layer comprises multiple blue-phase liquid crystal molecules which are driven by the electric field. The auxiliary material layer is configured on the second substrate and located between the second substrate and the blue-phase liquid crystal layer. Furthermore, the auxiliary material layer is not configured between the first substrate and the blue-phase liquid crystal layer. By equipping the auxiliary material layer on the single substrate, especially by equipping the auxiliary material layer on a color filtering substrate or the opposite substrate, the blue-phase liquid crystal display panel in the invention can have the driving voltage significantly reduced and the penetration rate improved.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, and in particular to a blue phase liquid crystal display panel. Background technique [0002] In 1888, Friedrich Reinitzer placed cholesterol-type benzoate (Cholesteric benzoate) in a polarizing microscope, and observed that cholesterol-type benzoate would show different colors (blue) in the homogeneous phase (Isotropic) and cholesterol phase (Cholesteric). Purple and blue), the color change between the homogeneous phase and the cholesterol phase only exists in a small temperature range (only about 1°C temperature range). In 1970 AD, many scientists confirmed that the aforementioned phenomenon is a new thermodynamically stable phase by using methods such as volumetric analysis and high-resolution differential scanning calorimeter, and called it the blue phase. [0003] The blue phase has three different phases, these three phases are represented as BP I, BP II, and BP III, and the temper...
