Title:
液晶表示装置
Document Type and Number:
Japanese Patent JP5061409
Kind Code:
B2
Abstract:
Light is input into an incident surface portion from a fluorescent lamp, and most of the light propagates in repetition directions. Since a length of an emission portion of the fluorescent lamp is shorter than that of the incident surface portion, there are areas to which no light propagates and dark portions generate in the repetition directions of a string of prisms. Since these dark portion generate out of the display area, a display quality is improved.
