Noiseless Liquid Crystal Display Backlight

      Disclosed is to put a sheet consists of a metal tape and a
reflection sheet on the inside of a lamp holder of backlight of a
Liquid Crystal Display (LCD) in order to improve a screen quality of
the LCD influenced by the backlight.

      The Figure shows the example of this new lamp holder.  The
sheet of reflection film and metal tape put on the inside of lamp
holder.  The sheet has metal tape outside and reflection film inside
from the lamp position.  Also, metal tape is connected with the
ground.

      Then lighting efficiency is increased by a reflection film, and
electrical noise from fluorescent lamp is shielded by metal tape in
the lamp holder.  Therefore, LCD screen using this new lamp holder
reduces bad influence from LCD backlight.
