Title: Transflective film and liquid crystal display device
Inventor: YOSHII KATSUMASA
IPC: G02B5/08
Filed: 2003-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a transflective film efficiently reflecting incident external light and a liquid crystal display device using the same.  <P>SOLUTION: An opening 32 formed on the transflective film 12 is adapted to approach an edge 36a of a rectangular pixel region 36. An interval t2 between three sides 32a out of the four sides of the rectangular opening 32 and the edge 36a of the pixel region 36 is set to be smaller than the width of one concave portion 31 formed on the transflective film 12. In the transflective film 12, a specified reflection performance is obtained by using the predetermined number of the concave portions 31, for example, four rows of the four concave portions as a unit. Therefore, when the interval t2 between the sides 32a of the opening and the edge 36a of the pixel region 36 is set to be smaller than the width of the one concave portion 31 formed on the transflective film 12, the concave portions 31 that scarcely contribute to reflection can be minimized, and the reflectance of the transflective film 12 is maximized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
