A fluorescent lamp with a lengthened lifetime that emits a reduced amount of ultraviolet light is presented. The lamp includes a discharge tube, a plurality of discharge electrodes and a discharge gas. The discharge tube is made of a material containing titanium oxide, and a fluorescent layer is deposited on an inner surface of the discharge tube. The discharge electrodes are made of a material containing a nickel-niobium alloy. The discharge electrodes are on end portions of the discharge tube, respectively. The discharge gas is in the discharge tube. A backlight assembly and a display device made with such fluorescent lamp is also presented.

A cold cathode fluorescent lamp includes a lamp tube, a fluorescent layer, an inner electrode, a lead wire and a conducting cap. The lamp tube contains a discharge gas. The fluorescent layer is formed on an inner surface of the lamp tube. The inner electrode is disposed inside of the lamp tube. The lead wire is electrically connected to the inner electrode and extends to an exterior portion of the lamp tube. The conducting cap is combined with the lamp tube, and electrically connected to the lead wire. As a result, a soldering process is not required. Further, a malfunction caused by an opening of a lamp wire is prevented.

A light guide plate includes a first optical member having a first light path-changing portion to separate a first light portion and a second light portion from a light, and a second optical member having a second light path-changing portion corresponding to the first light path-changing portion. The first optical member has a first refractive index against the first light portion of the light and a second refractive index against the second light portion of the light, and the second optical member has the first refractive index against the first and second light portions. Thus, brightness and brightness uniformity of an image displayed on a display apparatus may be improved, and a number of parts of the display apparatus may be reduced.

A display device comprises an optical module, a light source unit, a container and a display panel. The optical module comprises at least one optical member and a transparent adhesion member combined with the optical member. The optical member has a first modulus of elasticity, and the transparent adhesion member has a second modulus of elasticity that is substantially identical to the first modulus of elasticity. The light source unit is disposed in a light providing region of the display device to generate a light. The container receives the light source unit and the optical module. The display panel is received in the container and disposed in a display region of the display device. The display panel displays an image based on a light passing through the optical module.

A diffusing reflective polarizing film has a liquid crystal film and a diffusing layer. The liquid crystal film includes a cholesteric liquid crystal diffusely reflecting a first component of a light substantially in parallel with a twisted axis of the cholesteric liquid crystal and transmitting a second component of the light different from the first component. The diffusing layer is attached to the liquid crystal layer to diffuse light from the liquid crystal layer. Thus, the diffusely reflective polarizing film may improve brightness uniformity, thereby preventing a warping phenomenon of the diffusely reflective polarizing film.

An integral optical plate includes a convex lens plate, a microlens sheet and an adhesion element. The convex lens plate includes a first light incident surface into which light is incident and a first light-exiting surface disposed opposite the first light incident surface and on which a convex tens pattern is formed. The microlens sheet is disposed on the first light-exiting surface, and includes a microlens pattern. The adhesion element is disposed between the convex lens plate and the microlens sheet to combine the convex lens plate with the microlens sheet. The convex tens pattern includes a plurality of convex in lenses having a stripe shape extending lengthwise along the convex lens plate.

A light-guide plate (LGP) includes a light-incident surface, a light-facing surface, a light-emitting surface and a light-reflecting surface. The light-incident surface receives light. The light-facing surface has a smaller size than that of the light-incident surface. The light-facing surface faces the light-incident surface. The light-emitting surface is extended substantially perpendicular to the upper side of the light-incident surface. The light-emitting surface is connected to the upper edge of the light-facing surface. The light-reflecting surface has a plurality of first prism patterns that are formed parallel with the light-incident surface. The light-reflecting surface is extended from the base of the light-incident surface to be connected to the base of the light-facing surface. Therefore, a leakage of light that exits from the wedge-type LGP through a side surface of the wedge-type LGP is decreased, so that luminance is enhanced.
