Example Embodiment

[0026] Figure 2A to Figure 2E It is a flowchart of a liquid crystal alignment method according to an embodiment of the present invention. Please refer first Figure 2A The liquid crystal alignment method of this embodiment includes the following steps. First, a first substrate 110 and a second substrate 120 are provided. The first substrate 110 is, for example, an active device array substrate, and the second substrate 120 is, for example, a pair of substrates.

[0027] Then, like Figure 2B As shown, a liquid crystal layer 130 is provided between the first substrate 110 and the second substrate 120, wherein the liquid crystal layer 130 includes a liquid crystal composition 132, a monomer material 134, and a polymerization initiator (not shown). In addition, the liquid crystal composition 132 includes a plurality of liquid crystal molecules 133.

[0028] Next, an electric field is applied to align the liquid crystal molecules 133 in the liquid crystal composition 132 along a pre...

Abstract

The invention discloses a liquid crystal alignment method includes the following steps: providing a first substrate and a second substrate; providing a liquid crystal layer between the first substrate and the second substrate, wherein the liquid crystal layer includes a liquid crystal composition, a monomer material and a polymerization initiation agent; executing a first exposal proceeding , in order to allow parts of the monomer material to polymerize to form two polymer steadily alignment layers, respectively a first contact face located between the liquid crystal layer and the first substrate, and a second contact face between the liquid crystal layer and the second substrate, in order to allow a plurality of liquid crystal molecules in the liquid crystal composition to align along a pre-inclination angle; and executing a second exposal proceeding , in order to allow the surplus monomer material to polymerize, wherein the second exposal proceeding uses light with the principal wavelength between 290 nanometer to 340 nanometer to irradiate the surplus monomer material. The liquid crystal alignment method can boost the reliability of the liquid crystal display board.

Description

technical field [0001] The invention relates to a manufacturing method of a liquid crystal display panel, in particular to a liquid crystal alignment method. Background technique [0002] With the advancement of flat panel display technology and the advantages of light weight, small size and power saving of flat panel displays, flat panel displays have become more and more popular. Common flat panel displays include liquid crystal display (liquid crystal display, LCD), plasma display panel (plasma display panel, PDP), organic light emitting diode display (organic light emitting diode display, OLED display) and electrophoretic display (electrophoretic display, EPD), among which The penetration rate of liquid crystal display is the highest. [0003] The liquid crystal display includes a liquid crystal display panel (LCD panel) and a backlight module (backlight module), wherein the backlight module is used to provide a display light source to the liquid crystal display panel. ...
