Problems solved by technology
[0004] However, there is always a problem in the prior art including the above-mentioned invention: the transmittance and the reflectance are mutually limited, that is, if there is a high transmittance, the reflectance must be relatively low, resulting in poor contrast characteristics during reflection; If the reflectivity is high, the color filter film cannot be made too thick, so that the color characteristics of the transmission will be deteriorated

Abstract
The present invention discloses a semi-transmission-type liquid crystal displays, which comprises a lower polaroid, a lower transparent substrate, a color filter film, an insulator layer, a reflective film, a transparent conductive film, LCD, a second transparent conductive film, transparent substrates and an upper polarioid; the reflective film is provided with an opening. The present invention is characterized in that the reflective film is positioned above the color filter film; the reflective film and the transparent conductive film are arranged to be adjacent with each other; the insulating layer is arranged between the reflective film and the color filter film. The present invention has the main characteristics that the reflective film is positioned above the color filter film; the reflective film and the transparent conductive film are arranged to be adjacent with each other; the insulating layer is arranged between the reflective film and the color filter film; the present invention also discloses a LCD production method; the semi-transmission type liquid crystal display in the present invention can achieve black-and-white display with high reflective rate and high contrast when the backlighting is not lit, and can display the similar all-through bright colors when the backlight is lit.
Description
technical field [0001] The present invention relates to a reflective and transmissive dual-purpose color liquid crystal display device with reflective and transmissive functions, more specifically, to a semi-transmissive liquid crystal display with excellent display effect under transmissive and reflective working states and its manufacture method. Background technique [0002] There are many manufacturing methods of the existing semi-transmissive color liquid crystal display, mainly including semi-transmissive metal film type and reflective film opening type. The semi-transparent metal film type is seldom used due to its high cost, and the reflective film opening type is a commonly used method. This method can adjust the transmittance and reflectance by changing the size of the opening. [0003] For example, the Chinese invention patent titled "Semi-transmissive Liquid Crystal Display and Its Manufacturing Method" and patent No. CN200410040336.7 discloses a semi-transmissi...
