Display Panel Manufacturing Method And Liquid Crystal Display Device

A display panel manufacturing method, comprising the steps of:

• providing a first electrode plate, a second electrode plate opposing the first electrode plate, and an array substrate between the first and second electrode plates, where the array substrate comprises a first transparent electrode and a first alignment film;
• producing a first electrical field between the first and second electrode plates, and conducting a first photo-alignment on the first alignment film;
• providing a third electrode plate and a color film substrate opposing the third electrode plate, where the color film substrate comprises a second transparent electrode and a second alignment film, the second alignment film is positioned between the third electrode plate and the second transparent electrode;
• producing a second electrical field between the third electrode plate and the second transparent electrode, and conducting a second photo-alignment on the second alignment film;
• and
• joining the array substrate and the color-film substrate to form the display panel.

A liquid crystal display device, comprising a display panel and a backlight, wherein the display panel is manufactured by the steps of:
