REFLECTIVE SHEET FOR BACK LIGHT UNIT OF LIQUID CRYSTAL DISPLAY AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a reflection sheet which can be used for a backlight unit of a liquid crystal display. By integrating a second layer (12) which has an anti-static function onto one side or both sides of a first layer (11) which includes fine pores inside in order to have high reflexibility through coextrusion, the present invention makes at least one surface of the reflection sheet have an anti-static function which is equal to or less than 1*1011 Ω/cm^2 even in a high-temperature and high-humidity environment. By doing so, it is easy to control the attachment of foreign substances from the outside so that the provided reflection sheet for a backlight unit of a liquid crystal display having an anti-static function can resolve the problem of foreign substances coming in, being attached to a backlight unit, and causing optical defects on a liquid crystal display while the liquid crystal display is being manufactured and/or is in use. Therefore, the reflection sheet can be useful as a film for a reflection plate.
