A display device includes luminous and non-luminous areas. The display device includes a display element layer, an optical control layer, and a low reflective window, stacked in the order provided. The low reflective window has SCI reflectivity of 4.12% or less. The display element layer includes a pixel definition film where a pixel opening that does not overlap the luminous area is defined. A first electrode is exposed through the pixel opening. An emission layer is disposed on the first electrode. A second electrode is disposed on the emission layer. A low reflective layer is disposed on the second electrode and includes bismuth (Bi) and/or ytterbium (Yb). The optical control layer includes a color pattern part that does not overlap the luminous area, and an overcoat layer disposed on the color pattern part and overlapping the luminous and non-luminous areas.

A liquid crystal display includes a first substrate that includes a plurality of pixels, a second substrate facing the first substrate that includes a plurality of color filters, a position of each color filter on the second substrate respectively corresponding to a position over one of the pixels and a black matrix disposed between the color filters, and a liquid crystal layer disposed between the first substrate and the second substrate. The plurality of color filters includes a red color pixel displaying a red color, a green color pixel displaying a green color, and a blue color pixel displaying a blue color. The green color pixel includes a yellow portion including a yellow pigment and a green portion disposed on the yellow portion and including a green pigment.

A display panel includes a first substrate and a spaced apart second substrate and a protection or other additional film attached to an outer and laterally extending major surface of the first substrate. The first substrate includes a first base substrate having a major lateral surface subdivided into a display region and a peripheral region, a color filter member disposing on the first base substrate and having a plurality of color filters, a light blocking member disposing on the peripheral region of the first base substrate and an overcoating member disposing on the color filter member and on the light blocking member and extending to cover a sidewall surface of the light blocking member. The extend overcoating member helps block charged particles from reaching the light blocking member, thus preventing discoloration of the color filter due to influx of static electricity associated with the charged particles.

A liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The second substrate includes a buffer layer, and the buffer layer includes a recessed portion. A spacer is disposed between the first substrate and the second substrate, such that a portion of the spacer is extended into the recessed portion. A bottom surface of the recessed portion contacts an upper surface of the spacer. A shortest line crossing a center of the bottom surface of the recessed portion is longer than a longest line crossing a center of the upper surface of the spacer, by about 14 micrometers to about 20 micrometers.

A display apparatus includes a lower substrate, an upper substrate, a spacer and an image display layer. The spacer includes a main spacer, a first sub-spacer and a second sub-spacer. The main spacer has a height greater than that of the first and second sub-spacers. The second sub-spacer has an area wider than that of the main spacer and the first sub-spacer.

A mask includes a substantially transparent portion. The mask further includes a halftone portion abutting the substantially transparent portion, a light transmittance of the halftone portion being greater than 0% and less than 100%. The mask further includes a blocking portion abutting the halftone portion, a light transmittance of the blocking portion being less than the light transmittance of the halftone portion.
