The production of a defective liquid crystal display device is restrained and a yield of the liquid crystal display device is improved by detecting previously a flying of an adhesive on a reflection sheet of the liquid crystal display device. The liquid crystal display device comprises glass substrates, liquid crystal sealed between the glass substrates, and polarization films attached to the glass substrates and the like, wherein an adhesive for bonding the reflection sheet onto the back side of the liquid crystal display device is colored with a color which is different from that of the reflection sheet so as to easily visually recognize and detect the flying of the adhesive within an effective display region of the reflection sheet when the adhesive is printed.

Liquid crystal display device provided with reflection sheet and method of fabricating reflection sheet

ITO transparent electrodes having a low surface resistivity of 20-70 .OMEGA./.quadrature. are formed on a glass substrate. An additional ITO transparent electrode having a high surface resistivity of about 1 M.OMEGA./.quadrature. is formed so as to cover the low-resistivity transparent electrodes. Locally generated high-voltage static electricity is distributed in the high-resistivity transparent electrode, to prevent a spark between adjacent low-resistivity electrodes.
