Abstract

A backlight assembly includes a receiving container having a receiving space, a flat-type light source, an optical member, and an inverter. The flat-type light source has a plurality of light emitting spaces spaced apart from each other and is received into the receiving space. The optical member has a prism pattern formed in areas corresponding to areas between adjacent light emitting spaces and disposed at a light emitting direction of the flat-type light source. The inverter generates a voltage for the flat-type light source. The prism pattern 1o includes prisms having a substantially trigonal prism and continuously connected one after another. Thus, the backlight assembly may improve brightness uniformity thereof and have a reduced thickness.

Description

technical field

[0001] This application claims priority from Korean Patent Application No. 2005-6579 filed on Jan. 25, 2005, the entire contents of which are hereby incorporated by reference. Background technique

[0002] The invention relates to a backlight assembly, a manufacturing method of the backlight assembly, and a liquid crystal display (LCD) device with the backlight assembly. More particularly, the present invention relates to a backlight assembly with increased brightness and reduced thickness, a manufacturing method of the backlight assembly, and an LCD device having the same. Background technique

[0003] In general, a liquid crystal display (LCD) device displays images using electro-optical characteristics of liquid crystals, such as anisotropic refractive index and anisotropic dielectric constant. Compared with other display devices such as cathode ray tubes (CRTs) and plasma display panels (PDPs), LCD devices have features such as light weight, low power ...
