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.
