Abstract: The present disclosure relates to a display apparatus including a liquid crystal panel, first and second polarizing plates coupled to the front and rear of the liquid crystal panel, respectively, and a light absorbing layer on which light passed sequentially through the first polarizing plate, the liquid crystal panel is incident, wherein the light absorbing layer is disposed on a front surface of the second polarizing plate positioned in the front of the liquid crystal panel. The light absorbing layer includes a first resin layer, a second resin layer on which light passed through the first resin layer is incident, the second resin layer having a refractive index higher than that of the first resin layer, and light absorbing portions disposed on the first resin layer and configured to absorb a part of light passing through the light absorbing layer. Through this configuration, a viewing angle of the display apparatus is improved.

Abstract: A display apparatus includes a display panel receiving light from a light source. The display panel includes a liquid crystal panel, first and second polarizers respectively disposed on front and rear sides of the liquid crystal panel, and an optical layer disposed on a front surface of the second polarizer. The optical layer includes a first resin layer having light absorption portions for absorbing a portion of incident light, a second resin layer disposed on a front surface of the first resin layer, the second resin layer having a higher refractive index than the first resin layer, the second resin layer having light diffusion portions for diffusing light not absorbed by the light absorption portions.

Abstract: A display apparatus having a backlight unit and a display panel is disclosed. The display panel includes: a first electrode unit having a common electrode; a second electrode unit having a different polarity from the first electrode unit, and configured to include a plurality of pixel electrodes each forming an electric field using electric force of the first electrode unit; an insulator disposed between the first electrode unit and the second electrode unit so as to achieve electric insulation between the first electrode unit and the second electrode unit; and a liquid crystal unit located adjacent to the insulator in a manner that several pixel electrodes of the second electrode unit are inserted in the liquid crystal unit. The length or height of the pixel electrodes of the second electrode unit is ⅓ or higher of the length or height of the liquid crystal unit.
