Transmissive and reflective type liquid crystal display

A transmissive and reflective type LCD for partially reflecting and transmitting incident light, comprising:

• an LC cell including a first substrate, a second substrate having an inner surface that is arranged to face the first substrate, and a liquid crystal layer formed between the first substrate and the second substrate;
• a first polarizing plate formed on an outer surface of the first substrate;
• a second polarizing plate formed on an outer surface of the second substrate;
• a backlight arranged at a rear side of the first polarizing plate;
• and
• a transparent transflective film arranged between the first polarizing plate and the backlight and having a plurality of layers in which a first layer and a second layer having different refractivity indexes from each other,
• wherein the transmissive and reflective type LCD has a reflection light path along which the incident light is incident onto the LC cell from a front side of the LC cell, is reflected by the transflective film, and is output through the front side of the LC cell, and a transmission light path along which the incident light is incident onto the LC cell from a rear side of the LC cell, is transmitted through the transflective film, and is output through the front side of the LC cell.

A transmissive and reflective type LCD comprising:

• a first substrate on which a first transparent electrode is formed;
• a second substrate of which an inner surface is arranged facing the first substrate, the inner surface of the second substrate having a second transparent electrode thereon;
• a liquid crystal layer formed between the first substrate and the second substrate;
• a first polarizing plate formed on an outer surface of the first substrate;
• a second polarizing plate formed on an outer surface of the second substrate, opposite the inner surface of the second substrate;
• a backlight arranged at a rear side of the first polarizing plate;
• and
• a transparent transflective film arranged between the first polarizing plate and the backlight for partially reflecting and partially transmitting incident light.

A transmissive and reflective type LCD comprising:

• a first substrate on which a switching element and a transparent pixel electrode connected to the switching element are formed;
• a second substrate of which an inner surface is arranged facing the first substrate, the inner surface of the second substrate having a transparent common electrode thereon;
• a liquid crystal layer formed between the first substrate and the second substrate;
• a first polarizing plate formed on an outer surface of the first substrate;
• a second polarizing plate formed on an outer surface of the second substrate, opposite the inner surface of the second substrate;
• a backlight arranged at a rear side of the first polarizing plate;
• and
• a transparent transflective film arranged between the first polarizing plate and the backlight, said transparent transflective film having a plurality of layers in which a first layer and a second layer having different refractivity indexes from each other are alternatively stacked, the transparent transflective film partially reflecting and partially transmitting incident light.
