Title: Liquid crystal display device and information processing device provided with therewith
Inventor: BOKU CHINKO
IPC: G02F1/13
Filed: 2000-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of minimizing the size thereof by forming a chassis so that the thickness is gradually reduced from one side where a light source part is housed and located toward the other side. SOLUTION: A back light assembly 330 and a liquid crystal display panel assembly 350 are successively housed in the housing space of a mold frame 310, and closely connected to the mold frame 310 by a chassis 370 connected in opposition to the mold frame 310. The mold frame 310 and the chassis 370 are formed so that the depth of the housing space is reduced as it is farther from the position for housing the light source part 332 of the back light assembly 330. The reason for this is that the side thickness in the connection of the back light assembly 330 to the liquid crystal display panel assembly 350 is differed between one side and the other side. Accordingly, the liquid crystal display device is reduced in the thickness by the space occupied by the liquid crystal panel driving circuit part.
