Abstract

An LCD device comprises: a light irradiating portion; a microlens array having a plurality of microlenses for collecting light emitted from the light irradiating portion; and a liquid crystal panel having a plurality of unit pixels, each unit pixel matching with the plural microlenses, for displaying an image by passing light that has been collected into the microlens array through each unit pixel. According to this, a color degradation is reduced, a viewing angle is increased, a fabrication cost is reduced, and fabrication time is shortened.

Description

technical field [0001] The invention relates to a liquid crystal display device with a backlight panel module using a microlens array and a manufacturing method of the microlens array. Background technique [0002] Recently, there has been an increasing demand for LCD devices that can realize a large screen and high image quality. However, it is difficult to make an LCD device using a conventional cathode ray tube (CRT) small and realize a screen larger than a certain size. Therefore, a flat panel display (FPD) capable of being made small and realizing a large screen and high image quality has attracted public attention, and research on the FPD has been actively conducted. [0003] LCD is one of the most talked about flat panel displays. [0004] The LCD device utilizes electro-optic properties of liquid crystals in an intermediate state between liquid and solid states as a display device. The LCD device utilizes the principle that the arrangement of organic molecules of ...
