Embodiment Construction

[0040] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0041] Figure 4 is a cross-sectional view of a liquid crystal display device manufactured according to the liquid crystal dispensing method of the present invention. Figure 4In this method, before bonding the lower substrate 105 (i.e., TFT substrate) with multiple driving elements and the upper substrate 103 (i.e., CF substrate) with multiple color filters together, a series of droplets can be evenly spaced in A liquid crystal material 107 is dispensed on the surface of the lower substrate 105 having the driving elements. Furthermore, alternatively, the liquid crystal material 107 may be dispensed onto the upper substrate 103 with color filters. In addition, a seal pattern 109 may be formed along the outer periphery of the lower substrate. Alternatively, the seal pattern 109 may be formed on the periphery of the lower substrate 105 . In addition, the seal patte...

Abstract

A liquid crystal dispensing apparatus includes a liquid crystal material container, a nozzle positioned at a lower portion of the liquid crystal container and having at least one groove formed at an exterior surface thereof, and a valve system for transmitting liquid crystal material from the liquid crystal material container to the nozzle by a gas pressure supplied to the liquid crystal material container.

Description

technical field [0001] The invention relates to a liquid crystal distributing device, in particular to a liquid crystal distributing device capable of distributing accurate amounts of liquid crystals on a substrate and distributing the dispensed liquid crystals onto the substrate. Background technique [0002] Currently, the development of various portable electronic devices, such as mobile phones, personal digital assistants (PDAs), and notebook computers, requires flat panel display devices that make the electronic devices lightweight, small in size, and portable. Many different types of flat panel display devices have been developed for these portable electronic devices, including liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and vacuum fluorescent displays (VFDs). [0003] figure 1 is a cross-sectional view of a liquid crystal display device according to the prior art. figure 1 Among them, an LCD 1 includes a lower substr...
