  • Publication number: 20060192747
    Abstract: In an LCD apparatus (400) having simplified structure and improved luminance, a light supplying unit (100) supplies an LCD panel (280) with red light during a time corresponding to one-third of a frame, green light during the time and blue light during the time. A light reflective-transmissive unit is disposed between the light supplying unit (100) and the LCD panel assembly (200) to transmit the red light, the green light and the blue light and to reflect an external light from exterior of the LCD panel assembly (200). The LCD apparatus displays an image by means of white light as well as red light, green light and blue light, thereby improving luminance and simplifying structure.

  • Patent number: 7098480
    Abstract: Disclosed is a simplified method for manufacturing a liquid crystal display. A gate wire including a gate line, a gate pad, and a gate electrode are formed on a substrate. A gate insulating layer, a semiconductor layer, and an ohmic contact layer are sequentially deposited, and a photoresist layer is coated thereon. The photoresist layer is exposed to light through a mask and developed to form a photoresist pattern. At this time, a first portion of the photoresist pattern which is located between the source electrode and the drain electrode is thinner than a second portion which is located on the data wire, and the photoresist layer is totally removed on other parts. The thin portion is made by controlling the amount of irradiating light or by a reflow process to form a thin portion, and the amount of light is controlled by using a mask that has a slit, a small pattern smaller than the resolution of the exposure device, or a partially transparent layer.

  • Patent number: 6937303
    Abstract: Disclosed is a transmissive and reflective type LCD. In the LCD, a second substrate faces a first substrate. Liquid crystal layer is formed between the first and second substrate. A first polarizing plate is formed on outer surface of the first substrate. A second polarizing plate is formed on outer surface of the second substrate. A backlight is arranged at a rear side of the first polarizing plate. A transparent transflective film is arranged between the first polarizing plate and the backlight and has a plurality of layers where a first and a second layer each having different refractivity indexes are alternatively stacked. The transparent transflective film partially reflects and transmits incident light. By a restoring process occurring between the transflective film and the backlight, a predetermined amount of the incident light is transmitted through the transflective film repeatedly, so that transmissivity and light efficiency are enhanced.
