Abstract
Official abstract text for this publication.
A backlight unit includes a light guide plate; a wavelength conversion member disposed on a surface of the light guide plate; and a housing which houses the wavelength conversion member and is fused to the light guide plate.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing a display device, the method comprising: preparing a light guide plate, a wavelength conversion member to be disposed on a surface of the light guide plate, and a housing which houses the wavelength conversion member and is to be in contact with the light guide plate; and fusing the light guide plate and the housing to each other using a femtosecond laser. 2 . The method of claim 1 , further comprising: assembling the light guide plate and the housing, which are fused to each other, with a display panel. 3 . The method of claim 2 , further comprising: assembling the light guide plate and the housing, which are fused to each other, with a lower cover. 4 . The method of claim 1 , wherein the light guide plate and the housing, which are fused to each other, are directly in contact with each other to form a contact surface, and a bonding portion of the housing and the light guide plate is formed on the contact surface. 5 . The method of claim 4 , wherein the bonding portion comprises a plurality of bonding dots. 6 . The method of claim 5 , wherein each of the bonding dots comprises a central region and a peripheral region disposed outside the central region. 7 . The method of claim 6 , wherein a width of the central region is in a range of about 10 micrometers to about 20 micrometers. 8 . The method of claim 7 , wherein a width of the peripheral region is in a range of about 70 micrometers to about 100 micrometers. 9 . The method of claim 1 , wherein the light guide plate and the housing comprise a glass.
