Problems solved by technology

[0014] But in reflective mode, the above structure exhibits poor visibility and front reflection characteristics
That is to say, in the reflective mode, the light incident through the first substrate is specularly reflected at the semi-transmissive sheet, thus reducing the visibility of the light and narrowing its viewing angle.

Embodiment Construction

[0028] figure 1 is a cross-sectional view showing a transmissive liquid crystal display device 500 according to an embodiment of the present invention.

[0029] refer to figure 1 , the transmissive liquid crystal display device of the present invention includes: a light emitting component 100 , a liquid crystal display 200 , a first polarizer 300 and a second polarizer 400 .

[0030] The light emitting part 100 generates the first light L1. The light emitting component 100 is aimed at the back of the liquid crystal display 200 so as to emit the first light L1 to the liquid crystal display 200 .

[0031] The liquid crystal display 200 includes a first substrate 210 , a second substrate 220 opposite to the first substrate 210 , and a liquid crystal layer 230 interposed between the first substrate 210 and the second substrate 220 .

[0032] Such as image 3 As shown, the first substrate 210 includes a first glass substrate 211 . A TFT 212 functioning as a switching device an...

Abstract

Disclosed is a liquid crystal display device (700) capable of improving a display characteristic and a viewing angle as well as visibility in a reflection mode. A semi-transmissive film (600) is positioned between a light generating section (100) and a liquid crystal display panel (200) in order to partially transmit or reflect light supplied from an exterior. A polarizing plate (400), one surface of which is anti-glare treated, is positioned between the liquid crystal display panel (200) and the semi-transmissive film (600). The polarizing plate (400) diffuses light transmitted through or reflected from the semi-transmissive film. The display characteristic and viewing angle of the liquid crystal display device may be improved and reflectivity of light in the reflection mode may increase, so that visibility is improved.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device capable of improving display characteristics, viewing angle, and visibility in reflection mode. Background technique [0002] In the current era of information society, electronic display devices play an important role, and various electronic display devices are widely used in various industries. [0003] With the rapid development of semiconductor technology, various electronic devices with low driving voltage, low energy consumption, light weight and small size have been enriched. In this regard, it is required to make a smaller and lighter flat-panel display with low driving voltage and low power consumption in order to adapt to the new industrial environment. [0004] Among the currently developed displays, the liquid crystal display device has a smaller and lighter structure, and has low power consumption and low driving voltage, so ...
