In addition, liquid crystals also exhibit optical properties according to changes in an electric field. In the liquid crystal, the orientation of molecules forming the liquid crystal may change according to a change in an electric field. When an electric field is generated in the liquid crystal layer25, the liquid crystal molecules25aof the liquid crystal layer25may be disposed along the direction of the electric field. When the electric field is generated in the liquid crystal layer25, the liquid crystal molecules25amay be disposed irregularly or disposed along an alignment layer. As a result, the optical properties of the liquid crystal layer25may vary depending on the presence or absence of the electric field passing through the liquid crystal layer25.

At this time, that the coupling portion1225is located on one side of one light source1100with respect to the first direction Z does not necessarily mean that the center of the coupling portion1225and the center of the light source1100are located simultaneously on a straight line extending in the first direction Z. Particularly, it is sufficient that the coupling portion1225is located adjacent to a straight line passing through one light source1100in the first direction Z. That is, the coupling portion1225may be formed at a specific position, which is on a straight line passing through one light source1100in the first direction Z, on the board bar1220. Alternatively, the coupling portion1225may be disposed on a region, which is adjacent to the board bar1220within a predetermined distance from a straight line passing through one light source1100in the first direction Z, on the board bar1220. One light source1100may be one of the plurality of first side light sources1110or one of the plurality of second side light sources1120.

The coupling portion1225may be arranged parallel to either the first plurality of protrusions1222aor the plurality of second protrusions1222bwith respect to the first direction Z.

In other words, each of the plurality of bar fixers201may be located on one side, which is in the first direction Z, of one light source1100among the plurality of light sources1100mounted on the corresponding board bar1220. Each of the plurality of bar fixers201may be arranged side by side in the first direction Z with one light source1100among the plurality of light sources1100mounted on the corresponding board bar1220. Each of the plurality of bar fixers201may be arranged at a position parallel to either one of the plurality of first protrusions1222aor the plurality of second protrusions1222bon the corresponding board bar1220, with respect to the first direction Z.

Accordingly, the coupling portion1225in each of the plurality of board bars1220may be located on the central extending portion1221of each board bar1220and located on one side, which is in the first direction Z, of one light source (e.g., either the first side light source1110or the second side light source1120) among the plurality of light sources1100mounted on the board bar1220. In other words, the coupling portion1225in each of the plurality of board bars1220may be disposed at the center with respect to the width direction of each board bar1220, and may be disposed in a position parallel to one light source1100, which is among the plurality of light sources1100mounted on the board bar1220, with respect to the width direction.

In other words, at least some of the plurality of coupling portions1225provided on the plurality of board bars1220may be disposed adjacent to the end of the board bar1220. The end of the board bar1220may refer to one end of the board bar1220with respect to a direction, in which the board bar1220extends from the board body1210in the second direction Y, and may refer to one end opposite to the board body1210of the board bar1220. As the board bar1220is elongated from the board body1210, there is a risk that the end opposite to the board body1210may not be effectively supported by the board body1210. However, the bar fixer201may be located adjacent thereto and couple the coupling portion1225to the bottom chassis15. Accordingly, the end of the board bar1220may efficiently maintain the fixed position.

According to one or more embodiments, the coupling portion1225formed on each of the plurality of board bars1220may be arranged side by side. According to one or more embodiments, as shown inFIG.7, the coupling portion1225formed on each of the plurality of board bars1220may be arranged side by side in the first direction Z. Accordingly, the coupling portion1225formed on each of the plurality of board bars1220may be disposed on the central extending portion1221of each board bar1220and at the same time, disposed on a straight line connecting the light sources1100, which are arranged side by side among the plurality of light sources1100mounted on the plurality of board bars1220, in the first direction Z.

Therefore, the plurality of bar fixers201may be arranged side by side with each other. As shown inFIG.7, the plurality of bar fixers201may be arranged side by side in the first direction Z.

According to one or more embodiments, as shown inFIG.7, one board bar1220of the plurality of board bars1220may be fixed to the bottom chassis15by the plurality of bar fixers201, and the plurality of coupling portions1225may be formed on one board bar1220.

At this time, in one board bar1220, the plurality of coupling portions1225may be arranged side by side in the second direction Y. Therefore, the plurality of bar fixers201disposed on one board bar1220may be arranged side by side in the second direction Y.

According to one or more embodiments, among the plurality of coupling portions1225formed on a single board bar1220, some coupling portions1225may be formed adjacent to an end portion1220eof the board bar1220, and other some of the coupling portions1225may be formed at a position between the coupling portion1225, which is formed adjacent to the end portion1220eof the board bar1220, and the board body1210. Further, the plurality of coupling portions1225formed at positions adjacent to the end portion1220eof each of the plurality of board bars1220may be arranged side by side along the first direction Z.

FIGS.8and9illustrate one board bar1220among the plurality of board bars1220included in the display apparatus1according to one or more embodiments, but a description of characteristics of one board bar1220described above with reference toFIGS.8and9may be applied correspondingly to characteristics of each of the plurality of board bars1220.

FIGS.8and9illustrate one bar fixer201among the plurality of bar fixers201included in the display apparatus1according to one or more embodiments, but a description of characteristics of one bar fixer201described above with reference toFIGS.8and9may be applied correspondingly to characteristics of each of the plurality of bar fixers201.

Referring toFIGS.8and9, the plurality of light sources1100mounted on a single board bar1220included in the display apparatus1according to one or more embodiments may be spaced apart from the central extending portion1221.

According to one or more embodiments, the board bar1220may include the plurality of first side light sources1110disposed on one side with respect to the central extending portion1221of the board bar1220, and the plurality of second side light sources1120disposed on the other side with respect to the central extending portion1221of the board bar1220.

The board bar1220may include the power supply line1230(refer toFIG.4) configured to supply power to the plurality of light sources1100. The power supply line1230may be electrically connected to the plurality of light sources1100, and may supply power to drive each of the light sources1100or transmit control signals to the plurality of light sources1100.

The power supply line1230may include a first power supply line1231disposed along the position in which the plurality of first side light sources1110is arranged. The first line1231may be electrically connected to the plurality of first side light sources1110. The plurality of first side light sources1110may be electrically connected to each other through the first line1231.

According to one or more embodiments, the first line1231may be disposed at a position spaced apart from the center of the board bar1220with respect to the first direction Z. In other words, the first line1231may be arranged to be spaced apart from a straight line passing through the center, which is in the first direction Z, of the board bar1220in the second direction Y.

In this case, as shown inFIGS.8and9, the first line1231may be arranged to allow a portion of the first line1231to overlap the central extending portion1221. Alternatively, the first line1231may be spaced apart from the central extending portion1221and disposed outside the central extending portion1221.

The power supply line1230may include a second power supply line1232disposed along a position in which the plurality of second side light sources1120is arranged. The second line1232may be electrically connected to the plurality of second side light sources1120. The plurality of second side light sources1120may be electrically connected to each other through the second line1232.

According to one or more embodiments, the second line1232may be disposed at a position spaced apart from the center of the board bar1220with respect to the first direction Z. In other words, the second line1232may be arranged to be spaced apart from a straight line passing through the center, which is in the first direction Z, of the board bar1220in the second direction Y.

In this case, as shown inFIGS.8and9, the second line1232may be arranged to allow a portion of the second line1232to overlap the central extending portion1221. Alternatively, the second line1232may be spaced apart from the central extending portion1221and disposed on the outside of the central extending portion1221.

According to one or more embodiments, the first line1231and the second line1232may be electrically connected to each other at one end of the board bar1220, the board body1210, etc. According to one or more embodiments, the first line1231and the second line1232may be connected to each other to form a part of a closed circuit.

The coupling portion1225may be arranged to be spaced apart from the first line1231to prevent interference with the first line1231, that is, to avoid the first line1231. Particularly, the coupling portion1225may be disposed at a position spaced apart from the first line1231in the first direction Z. According to one or more embodiments, the coupling portion1225may be disposed on the lower side of the first line1231(−Z direction).

The coupling portion1225may be arranged to be spaced apart from the second line1232to prevent interference with the second line1232, that is, to avoid the second line1232. Particularly, the coupling portion1225may be disposed at a position spaced apart from the second line1232in the first direction Z. According to one or more embodiments, the coupling portion1225may be disposed above the second line1232(+Z direction).

Because the bar fixer201is disposed at the coupling portion1225of the board bar1220, it is appropriate that the coupling portion1225and the power supply line1230do not interfere with each other in order to smoothly supply power to the light source1100. Particularly, as will be described later, the coupling portion1225may include a board hole1225h. The board hole1225hmay be formed in a shape through which the board bar1220is penetrated in the front and rear direction (X direction) and thus it may be required that the coupling portion1225be provided in a location that avoids the power supply line1230.

Accordingly, the coupling portion1225may be disposed between the first line1231and the second line1232of the power supply line1230to avoid the power supply line1230.

Meanwhile, the first line1231and the second line1232may each be formed to have a predetermined thickness. In addition, according to some embodiments, the first line1231or the second line1232may each be formed to have a plurality of patterns.

Therefore, in order to prevent the coupling portion1225from interfering with the power supply line1230, it is required that the coupling portion1225be provided to have a sufficient distance from the power supply line1230, such as the first line1231and the second line1232. When the coupling portion1225is disposed adjacent to a part of the power supply line1230, such as the first line1231or the second line1232, there is a risk that the power supply line1230is damaged in the process in which the bar fixer201is mounted on the coupling portion1225. Further, when the coupling portion1225is disposed adjacent to a part of the power supply line1230, a risk, in which the board hole1225hoverlaps the position of the power supply line1230, is increased due to an error that is generated in the process in which the board hole1225his formed at the position of the coupling portion1225of the board bar1220. Accordingly, there is a risk that the power supply line1230is damaged.

Alternatively, the above-mentioned structure of the inclined guide240may be provided to be symmetrical with respect to the center line passing through the center of the bar fixer201in the second direction

Y. The inclined guide240may be provided to have a structure symmetrical with respect to the center of the bar fixer201, and thus when a work, in which the bar fixer201is fixed to the board bar1220, is performed, a restriction due to the direction of the bar fixer201about the board bar1220may be reduced and a manufacturer performing this work may have little consideration for the direction of the bar fixer201. Work efficiency for coupling the bar fixer201to the board bar1220may be improved and thus manufacturing time and manufacturing costs may be reduced.

The bar fixer201may be removably mounted on the mounting portion15a. In other words, the bar fixer201may be provided to be mountable on the mounting portion15aand at the same time, the bar fixer201may be removable again from the mounting portion15ain a state in which the bar fixer210is mounted on the mounting portion15a. That is, while the bar fixer201is mounted on the mounting portion15a, the bar fixer201may be separated from the mounting portion15aby sliding in a direction away from the mounting portion15a.

With this structure, the board bar1220may be mounted on the bottom chassis15by sliding with respect to the bottom chassis15, and similarly, the light source board1200may be mounted on the bottom chassis15by sliding with respect to the bottom chassis15. With this structure, the board bar1220mounted on the bottom chassis15may be separated from the bottom chassis15by sliding in a direction that is opposite to a direction in which the board bar1220is moved when being mounted.
