Embodiment Construction

[0038] A liquid crystal display according to an exemplary embodiment of the present invention will now be described.

[0039] figure 1 is a cross-sectional view illustrating a liquid crystal display 1000 according to an exemplary embodiment of the present invention.

[0040] Such as figure 1 As shown, a liquid crystal display 1000 according to an exemplary embodiment of the present invention includes a lower substrate 110, a thin film transistor 120, a storage capacitor 130, a spacer 140, a liquid crystal 210, an upper substrate 310, a black matrix 320, a color filter 330 and a common electrode 340 .

[0041] The lower substrate 110 is an original plate on which the thin film transistor 120 is formed. Since the light of the backlight unit (BLU) is transmitted through the lower substrate 110, the material of the lower substrate 110 should be transparent. Therefore, it is usually made of glass, and its thickness is usually about 0.5 to 0.7mm. For the lower substrate 110, a ...

Abstract

A liquid crystal display and a manufacturing method thereof. The liquid crystal display includes a storage capacitor having a metal electrode as a reflector. The liquid crystal display may include a color filter and / or a black matrix on a reflective region of a second substrate corresponding to the storage capacitor on a first substrate. Light is reflected from the reflective region to transmit through liquid crystals between the first and second substrates. An organic film may be on the second substrate.

Description

technical field [0001] The invention relates to a liquid crystal display and a manufacturing method thereof. Background technique [0002] In general, liquid crystal displays can be classified into transmissive liquid crystal displays using a backlight as a light source and reflective liquid crystal displays using natural light as a light source. Transmissive LCDs use a backlight as a light source to produce bright images even in dark environments. However, in a bright environment, it is difficult to operate a transmissive LCD and consumes a lot of power. [0003] On the other hand, since reflective LCDs do not include a backlight, this reduces power consumption, but cannot be used in very dark environments. [0004] Alternatively, a transflective liquid crystal display can overcome the above-mentioned limitations of reflective liquid crystal displays. A transflective liquid crystal display has two areas, a reflective area and a transmissive area, within a unit pixel, so ...
