The internal angle formed by the third side 185 and the fourth side 186 at the facing portion 182 is 270 degrees. The other five interior angles are each 90 degrees.
One or more notches are formed in the cover 181 . In this example, the cover 181 is formed with a plurality of notches. A plurality of notches are formed in the edge of the facing portion 182 . The plurality of cutouts are formed so as to correspond to the plurality of connectors of drive section 141 . Therefore, in this example, the facing portion 182 is formed with three notches. Specifically, a first notch 191 , a second notch 192 , and a third notch 193 are formed in the facing portion 182 .

The first notch 191 is formed on the third side 185 . The first notch 191 is formed so as to divide the third side 185 . In this example, the shape of the first notch 191 is a trapezoid when the liquid crystal display 51 is viewed from behind. The first notch 191 is formed so as to be recessed from the third side 185 toward the panel connector 163 when the liquid crystal display 51 is viewed from the rear. Therefore, the first notch 191 corresponds to the panel connector 163 . A first notch 191 indicates the position of the panel connector 163 .

The second notch 192 is formed on the fifth side 187 . The second notch 192 is formed so as to divide the fifth side 187 . In this example, the shape of the second notch 192 is a trapezoid when the liquid crystal display 51 is viewed from behind.

Specifically, the second notch 192 is recessed from the fifth side 187 toward the input light source connector 165 when the liquid crystal display 51 is viewed from the rear.

A second cutout 192 exposes the light source connector. Specifically, the second cutout 192 exposes the input light source connector 165 . Thus, the second notch 192 corresponds with the input light source connector 165 . A second notch 192 indicates the position of the input light source connector 165 .

A third notch 193 is formed on the fifth side 187 . The third notch 193 is formed so as to divide the fifth side 187 . The shape of the third notch 193 is a trapezoid when the liquid crystal display 51 is viewed from behind. The third notch 193 is formed so as to be recessed from the fifth side 187 toward the light source connector when the liquid crystal display 51 is viewed from the rear. Specifically, the third notch 193 is recessed from the fifth side 187 toward the output light source connector 166 when the liquid crystal display 51 is viewed from the rear.

A third cutout 193 exposes the light source connector. Specifically, third cutout 193 exposes output light source connector 166 . As such, the third notch 193 corresponds to the output light source connector 166 . A third notch 193 indicates the position of the output light source connector 166 .

In this example, the first notch 191, the second notch 192, and the third notch 193 form the first side 183, the second side 184, the third side 185, the fourth side 186, the fifth side 187, and the sixth side. A side different from side 188 is formed in opposing portion 182 . Therefore, in this example, the opposing portion 182 includes the first edge 183, the second edge 184, the third edge 185, the fourth edge 186, the fifth edge 187, and the sixth edge 188 as edges, as well as the first edge. It has a side by the notch 191 , a side by the second notch 192 , and a side by the third notch 193 .

In this example, the opposing portion 182 has a seventh side 194 , an eighth side 195 and a ninth side 196 as sides formed by the first notch 191 . The seventh side 194 and the ninth side 196 are connected to the third side 185 . Specifically, one of the two third sides 185 divided by the first notch 191 is connected to the seventh side 194 and the other is connected to the ninth side 196 . In this example, the seventh side 194 and the ninth side 196 correspond to the first side 183, the second side 184, the third side 185, the fourth side 186, and the fifth side when the liquid crystal display 51 is viewed from the rear. 187 and the sixth side 188 are oblique. The eighth side 195 continues to the seventh side 194 and the ninth side 196 . The eighth side 195 is parallel to the first side 183 , the third side 185 and the fifth side 187 and perpendicular to the second side 184 , the fourth side 186 and the sixth side 188 .

The facing portion 182 has a first facing portion 198 and a second facing portion 199 . The first opposing portion 198 includes a first side 183, a second side 184, a third side 185, a fourth side 186, a fifth side 187, a sixth side 188, a seventh side 194, an eighth side 195, and a ninth side. 196 , a side formed by the second cutout 192 and a side formed by the third cutout 193 . The first facing portion 198 is a portion of the facing portion 182 that does not come into contact with the driving portion 141 . Therefore, the first facing portion 198 is separated from the drive substrate 142 . Therefore, a space is formed between the first facing portion 198 and the driving substrate 142 .

When a load is applied to the first opposing portion 198, the first opposing portion 198 may deform. When the deformed first opposing portion 198 contacts the driving substrate 142 , a load is applied to the driving substrate 142 . In this regard, in this example, since the first facing portion 198 is separated from the drive substrate 142, the risk of the first facing portion 198 contacting the drive substrate 142 is reduced. That is, the possibility that a load is applied to the panel circuit 143 and the light source circuit 144 is reduced. Therefore, the panel circuit 143 and the light source circuit 144 are protected.

Since the first facing portion 198 is separated from the drive board 142, the drive board 142 and the cover 181 are insulated. An insulating sheet may be attached to the surface of the first facing portion 198 that faces the driving substrate 142 . In this case, the driving substrate 142 and the cover 181 are further insulated.

The second facing portion 199 is a portion recessed from the first facing portion 198 toward the drive substrate 142 . That is, the second facing portion 199 is a portion that protrudes from the first facing portion 198 toward the driving substrate 142 . The second facing portion 199 is adjacent to the first notch 191 . The second facing portion 199 constitutes the eighth side 195 .

As shown in FIG. 10 , the second facing portion 199 faces the panel connector 163 . The second facing portion 199 contacts the panel connector 163 . The second facing portion 199 contacts the panel connector 163 so as to press the panel connector 163 against the rear surface 93 . Thereby, the panel connector 163 supports the cover 181 when a load is applied to the cover 181 . This reduces the risk of deformation of the cover 181 . Specifically, when a load is applied to the first facing portion 198 , the panel connector 163 receives the load via the second facing portion 199 . This reduces the risk of deformation of the first facing portion 198 . Therefore, the possibility that the first facing portion 198 contacts the drive substrate 142 is reduced.

A second facing portion 199 covers the panel connector 163 . That is, when the liquid crystal display 51 is viewed from the rear, the panel connector 163 is shielded by the second facing portion 199 . Therefore, it may be difficult to connect the cable to the panel connector 163 . In this regard, in this example, the position of the panel connector 163 is indicated by the first notch 191 . This makes it easy to connect a cable to the panel connector 163 even when the panel connector 163 is shielded by the second facing portion 199 .

As shown in FIG. 12, cover 181 has legs 201 . Legs 201 extend from the edge of facing portion 182 toward rear surface 93 . Specifically, legs 201 extend from an edge of first facing portion 198 toward rear surface 93 . In this example, the legs 201 extend from each of the second side 184 , the third side 185 , the fourth side 186 , the fifth side 187 , the sixth side 188 , the seventh side 194 and the ninth side 196 .

Legs 201 contact rear surface 93 . As a result, the facing portion 182 and the rear wall 121 are kept apart from each other by a predetermined distance. That is, a space is formed between the cover 181 and the drive board 142 . Specifically, a space is formed between the first facing portion 198 and the driving substrate 142 .

The leg 201 contacts the receiving part. Specifically, some of the legs 201 contact the first receiving portion 123 , the second receiving portion 124 , and the third receiving portion 125 . In this example, the leg portion 201 contacts the first receiving portion 123, the second receiving portion 124, and the third receiving portion 125 from above. Thereby, the cover 181 is supported by the receiving portion.

In this example, the first leg 202 is the leg 201 that contacts the first receiving portion 123 among the plurality of legs 201 . Among the plurality of legs 201 , the leg 201 that contacts the second receiving portion 124 is the second leg 203 . Of the plurality of legs 201 , the leg 201 that contacts the third receiving portion 125 is the third leg 204 .

First leg 202 is leg 201 extending from third side 185 . The first leg portion 202 extends from one of the two third sides 185 divided by the first notch 191 that is continuous with the second side 184 .

The second leg 203 is the leg 201 extending from the fifth side 187 . The second leg portion 203 extends from one of the three fifth sides 187 divided by the second cutout 192 and the third cutout 193 that is continuous with the fourth side 186 .

A third leg 204 is the leg 201 extending from the fifth side 187 . The third leg portion 204 extends from the side located between the second cutout 192 and the third cutout 193 among the three fifth sides 187 divided by the second cutout 192 and the third cutout 193 . Extend.

As shown in FIG. 10, first leg 202 has first leg portion 206 and second leg portion 207 . Not only the first leg 202 , but also the second leg 203 and the third leg 204 have a first leg portion 206 and a second leg portion 207 . In this example, legs 201 other than leg 201 extending from second side 184 and leg 201 extending from fifth side 187 have first leg portion 206 and second leg portion 207 . Leg 201 extending from second side 184 and leg 201 extending from fifth side 187 have only first leg portion 206 and do not have second leg portion 207 .

A first leg portion 206 extends from an edge of the opposing portion 182 . Specifically, first leg portion 206 extends from an edge of first opposing portion 198 . A first leg portion 206 extends forward or toward the rear surface 93 from the facing portion 182 .

A second leg portion 207 extends from the distal end of the first leg portion 206 . A second leg portion 207 bends from the first leg portion 206 . A second leg portion 207 extends along the rear surface 93 . In this example, the second leg portion 207 extends downward.

The second leg portion 207 of the first leg 202 , the second leg 203 and the third leg 204 is inserted between the rear surface 93 and the second receiving portion 127 . As a result, the second leg portion 207 contacts the first receiving portion 126 . The second leg portion 207 contacts the first receiving portion 126 so that the receiving portion supports the cover 181 . Contact of the second leg portion 207 with the second receiving portion 127 reduces the risk of the cover 181 coming off the case 91 .

The width of the second leg portion 207 is wider than the width of the first receiving portion 126 . That is, for the first leg portion 202 and the first receiving portion 123 , the width of the second leg portion 207 is wider than the width of the first receiving portion 126 . Regarding the second leg 203 and the second receiving portion 124 , the width of the second leg portion 207 is wider than the width of the first receiving portion 126 . Regarding the third leg 204 and the third receiving portion 125 , the width of the second leg portion 207 is wider than the width of the first receiving portion 126 . Accordingly, even if the cover 181 shifts to the left or right when the liquid crystal display 51 is viewed from the rear, the contact between the leg portion 201 and the receiving portion is maintained. Therefore, the receiving portion can easily support the leg portion 201 .

As shown in FIGS. 8 and 9, cover 181 has one or more hooks 211 . In this example, the hook 211 is a member for attaching the cover 181 to the case 91 . Hooks 211 extend from the edges of opposing portion 182 . Specifically, hook 211 extends from an edge of first opposing portion 198 . In this example, hook 211 extends from first side 183 .

Hook 211 is inserted into mounting hole 117 . Thereby, the cover 181 is attached to the case 91 . Specifically, the hook 211 is inserted into the mounting hole 117 toward the inside of the case 91 . That is, in this example, the hook 211 is inserted into the mounting hole 117 from above. The hook 211 is inserted into the mounting hole 117 so as to fill the step 111 .

The number of hooks 211 corresponds to the number of mounting holes 117 . Therefore, the cover 181 has four hooks 211 in this example. The four hooks 211 are arranged in a row on the first side 183 at predetermined intervals.

Hook 211 has a first hook portion 212 and a second hook portion 213 . The first hook portion 212 extends forward from the edge of the facing portion 182 . Specifically, first hook portion 212 extends from an edge of first opposing portion 198 . A second hook portion 213 extends from the tip of the first hook portion 212 . The second hook portion 213 bends from the first hook portion 212 . In this example, the second hook portion 213 extends downward. Second hook portion 213 is inserted into mounting hole 117 .

The width of the second hook portion 213 is narrower than the width of the mounting hole 117 . In this case, it is easier to insert the second hook portion 213 into the mounting hole 117 than when the width of the second hook portion 213 and the width of the mounting hole 117 match.

Hook 211 has a hook surface 214 . Hook surface 214 is a surface that extends from the edge of facing portion 182 . Hook surface 214 faces outward at hook 211 . In this example, the hook surface 214 faces upward. The hook surface 214 is flush with the first surface 112 . Therefore, the edge of the facing portion 182 is flush with the first surface 112 . As a result, the hook 211 does not protrude from the first surface 112, so that the liquid crystal display 51 can be made compact.

In this example, the cover 181 is attached to the case 91 by supporting the leg portion 201 on the receiving portion and inserting the hook 211 into the attachment hole 117 . In this case, the cover 181 is less likely to come off from the case 91 than when the cover 181 is attached to the case 91 using only one of the legs 201 or the hooks 211 .

As shown in FIGS. 12 and 13, cover 181 has one or more protrusions 221 . The protrusion 221 protrudes from the facing portion 182 . Specifically, the protruding portion 221 protrudes from the first facing portion 198 toward the driving substrate 142 . The projecting portion 221 projects so as to be recessed from the first opposing portion 198 . The protruding portion 221 protrudes from the first opposing portion 198 so as to be recessed in a truncated cone shape.

The tip of the projecting portion 221 contacts the driving substrate 142 . The projecting portion 221 contacts the component surface 161 . The protruding portion 221 contacts a portion of the component surface 161 where no circuit is mounted. That is, the projecting portion 221 contacts a portion of the component surface 161 where the panel circuit 143 and the light source circuit 144 are not mounted. The projecting portion 221 contacts, for example, the perimeter of the through hole 158 . It can also be said that the protrusion 221 extends toward the through hole 158 .

The protrusion 221 separates the facing portion 182 and the rear wall 121 by contacting the drive substrate 142 . That is, the protruding portion 221 forms a space between the facing portion 182 and the drive substrate 142 in the same manner as the leg portion 201 . Therefore, when a load is applied to the cover 181 , the drive substrate 142 receives the load via the projecting portion 221 . This reduces the risk of deformation of the cover 181 . Therefore, the risk of the cover 181 contacting the panel circuit 143 or the light source circuit 144 is reduced.

In this example, the number of protrusions 221 corresponds to the number of through holes 158 . Therefore, the cover 181 has five protrusions 221 in this example. The projecting portion 221 is positioned so as to overlap the through hole 158 when the liquid crystal display 51 is viewed from the rear.

In this example, the five protruding portions 221 are arranged in the cover 181 near the second side 184, near the corner between the third side 185 and the fourth side 186, near the corner between the fifth side 187 and the sixth side 188, It is positioned near the corner between the sixth side 188 and the first side 183 and near the center point C1 of the cover 181 . The center point C1 indicates the center position of the cover 181 when the liquid crystal display 51 is viewed from behind.

At least one projecting portion 221 among the plurality of projecting portions 221 is positioned within a predetermined distance L1 from one of the plurality of connectors of the driving portion 141 when the liquid crystal display 51 is viewed from the front. good too. In this example, the distance between the output light source connector 166 and the protrusion 221 located near the corner between the fifth side 187 and the sixth side 188 is the specific distance L2. The specific distance L2 is smaller than the predetermined distance L1. Therefore, the protruding portion 221 positioned near the corner between the fifth side 187 and the sixth side 188 is positioned within the predetermined distance L1 from the output light source connector 166 . Not limited to this, other protruding portions 221 may be positioned within a predetermined distance L1 from either connector.

In the drive board 142, a load is likely to be applied around the connector when a cable is connected to the connector. Therefore, in the drive board 142, the periphery of the connectors, that is, the periphery of the panel connector 163, the periphery of the input light source connector 165, and the periphery of the output light source connector 166 are likely to be displaced when the cables are connected. In particular, when a cable is inserted into the connector, the drive board 142 tends to rise from the rear surface 93 due to the load applied to the connector. In this case, the panel circuit 143 and the light source circuit 144 may contact the cover 181 .

In this respect, the protrusion 221 can effectively hold down the drive substrate 142 by positioning the protrusion 221 in the vicinity of the connector. In this example, since the projecting portion 221 is positioned near the output light source connector 166, it is possible to reduce the possibility that the periphery of the output light source connector 166 is displaced. Thereby, the space formed between the drive board 142 and the cover 181 is maintained.

At least one protrusion 221 among the plurality of protrusions 221 is positioned between one of the plurality of connectors and the center line D1 in the upper and lower directions when the liquid crystal display 51 is viewed from the rear. In this example, the protrusion 221 positioned near the corner between the fourth side 186 and the fifth side 187 and the protrusion 221 positioned near the corner between the fifth side 187 and the sixth side 188 are the input light source connector. 165 and output light source connector 166 and centerline D1. Specifically, when the liquid crystal display 51 is viewed from the rear, the center position of the protruding portion 221 positioned near the corner between the fourth side 186 and the fifth side 187 is positioned above the light source connector and is positioned on the center line D1. located below. The central position of the protruding portion 221 positioned near the corner between the fifth side 187 and the sixth side 188 is positioned above the light source connector and below the center line D1. The center line D1 is an imaginary line that vertically bisects the cover 181 when the liquid crystal display 51 is viewed from the rear. The center line D1 passes through the center point C1 and extends left and right when the liquid crystal display 51 is viewed from behind.

One or more insertion holes 222 are formed in the cover 181 . The insertion hole 222 is a hole into which a screw 223 for fixing the cover 181 to the case 91 is inserted. Therefore, the insertion hole 222 overlaps the through hole 158 . Therefore, the number of insertion holes 222 corresponds to the number of through holes 158 . That is, in this example, the number of insertion holes 222 corresponds to the number of protrusions 221 . In this example, five insertion holes 222 are formed in the cover 181 . In this example, the insertion hole 222 is formed in the projecting portion 221 . The insertion hole 222 opens at the tip of the projecting portion 221 .

As shown in FIG. 13, the case 91 is formed with a threaded hole 224 into which a screw 223 is inserted. A threaded hole 224 is formed in the rear wall 121 . Insertion hole 222 overlaps through hole 158 and screw hole 224 . A screw 223 is screwed into the threaded hole 224 .

Next, the operation and effects of the above embodiment will be described.
(1) The second facing portion 199 faces the panel connector 163 and contacts the panel connector 163 . Panel connector 163 supports cover 181 by contacting second facing portion 199 . Therefore, when a load is applied to the cover 181, the risk of deformation of the cover 181 is reduced. Therefore, the cover 181 protects the circuits mounted on the drive board 142 .

(2) The cover 181 forms a space between the drive board 142 and the first facing portion 198 by contacting the rear surface 93 with the leg portion 201 . That is, the driving substrate 142 and the first facing portion 198 are separated. Therefore, even if the cover 181 is deformed by applying a load to the cover 181 , the first facing portion 198 is less likely to come into contact with the drive substrate 142 .

(3) The projecting portion 221 contacts a portion of the drive substrate 142 where the panel circuit 143 and the light source circuit 144 are not mounted. This reduces the risk of deformation of the cover 181 when a load is applied to the cover 181 due to the protrusion 221 coming into contact with the drive board 142 . The panel circuit 143 and the light source circuit 144 are protected by the cover 181 because the protruding portion 221 contacts a portion of the drive substrate 142 that does not interfere with the panel circuit 143 and the light source circuit 144 .

(4) The cover 181 is formed with a second cutout 192 and a third cutout 193 as cutouts for exposing the light source connector. According to this, the input light source connector 165 and the output light source connector 166 are exposed. Therefore, it is easy to connect a cable extending from the sub-board 72 to the input light source connector 165 . Also, it is easy to connect the light source cable 172 to the output light source connector 166 .

(5) The cover 181 has a facing portion 182 facing the drive board 142 , hooks 211 extending from the edge of the facing portion 182 , and legs 201 extending from the edge of the facing portion 182 toward the rear surface 93 . The cover 181 is attached to the case 91 by inserting the hooks 211 into the attachment holes 117 and by bringing the leg portions 201 into contact with the receiving portions. In this case, the cover 181 is attached to the case 91 with two elements, the hook 211 and the leg portion 201 . According to this, the cover 181 is less likely to come off from the case 91 than when the cover 181 is attached to the case 91 by either the hook 211 or the leg portion 201 . Therefore, the cover 181 protects the circuits mounted on the drive board 142 .

(6) The receiving portion protrudes from the rear surface 93 and contacts the cover 181 from below by contacting the leg portion 201 . The hook 211 is inserted into the mounting hole 117 so as to face the inside of the case 91 . According to this, the cover 181 is supported by the case 91 from below by inserting the hooks 211 into the mounting holes 117 and by the contact of the leg portions 201 with the receiving portions. That is, the case 91 receives the load of the cover 181 due to gravity. This makes it difficult for the cover 181 to come off from the case 91 .

(7) the width of the second leg portion 207 is wider than the width of the first receiving portion 126; This makes it easier for the receiving portion to support the leg portion 201 . This makes it difficult for the cover 181 to come off from the case 91 .

(8) By inserting the hook 211 into the mounting hole 117 so as to face the inside of the case 91, the cover 181 is mounted on the case in a state where the edge of the facing portion 182 and the first surface 112 are flush with each other. Attached to 91. According to this, when the liquid crystal display 51 is viewed from the rear, the edge of the facing portion 182 does not protrude from the side surface of the case 91 . Therefore, when the gaming machine 11 is assembled, for example, the risk of the cover 181 coming off from the case 91 due to the edge of the opposing portion 182 being caught by another member is reduced. Therefore, the cover 181 protects the circuits mounted on the drive board 142 .

(9) The width of the mounting hole 117 is wider than the width of the second hook portion 213 . This makes it easy to insert the second hook portion 213 into the mounting hole 117 . Therefore, it is easy to attach the cover 181 to the case 91 .

(10) The panel cable 171 extends from the outside of the case 91 into the inside of the case 91 so as to pass between the mounting holes 117 when the liquid crystal display 51 is viewed from a position facing the first side surface 94 . This makes it difficult for the panel cable 171 to interfere with the hook 211 . Therefore, the panel cable 171 is less likely to be loaded. As a result, a load is less likely to be applied to the panel circuit 143 connected to the panel cable 171 . Therefore, the circuits mounted on the drive substrate 142 are protected.

(11) The panel cable 171 extends from the outside of the case 91 toward the inside of the case 91 by passing between the frame 101 and the holder 102 . According to this, the panel cable 171 can be routed from the outside of the case 91 toward the inside of the case 91 without providing the case 91 with a hole through which the panel cable 171 passes.

(12) Panel cable 171 passes between frame 101 and holder 102 so as not to overlap fixing hole 116 when liquid crystal display 51 is viewed from a position facing first side surface 94 . This makes it difficult for the panel cable 171 to interfere with the projection 135 inserted into the fixing hole 116 . Therefore, the panel cable 171 is less likely to be loaded.

(13) At least one protrusion 221 among the plurality of protrusions 221 is positioned within a predetermined distance L1 from one of the plurality of connectors when the liquid crystal display 51 is viewed from the rear. A load is likely to be applied to the drive board 142 around the connector when a cable is connected to the connector. Therefore, the area around the connector on the drive board 142 is likely to be displaced when the cable is connected.

According to this, the protrusion 221 is positioned closer to the connector than when the protrusion 221 is positioned away from the connector by the predetermined distance L1. Positioning the protruding portion 221 at a position close to the connector reduces the possibility that the periphery of the connector on the drive board 142 is displaced when the cable is attached or detached. In this example, the protruding portion 221 positioned near the corner between the fifth side 187 and the sixth side 188 is positioned near the output light source connector 166 . This reduces the possibility that the periphery of the output light source connector 166 on the drive board 142 is displaced when the light source cable 172 is connected. As a result, the space formed between the component surface 161 and the cover 181 is maintained. Therefore, the panel circuit 143 and the light source circuit 144 are protected.

(14) At least one protrusion 221 among the plurality of protrusions 221 is positioned vertically between one of the plurality of connectors and the center line D1 when the liquid crystal display 51 is viewed from the rear. . In this example, the protruding portion 221 positioned near the corner between the fourth side 186 and the fifth side 187 and the protruding portion 221 positioned near the corner between the fifth side 187 and the sixth side 188 are arranged vertically, It is located between the light source connector and the centerline D1. According to this, it is easy to maintain the space formed between the component surface 161 and the cover 181 by the projecting portion 221 . This protects the panel circuit 143 and the light source circuit 144 .

(15) The connector has a receptacle into which a cable is inserted. That is, the panel connector 163 has a receptacle 164 , the input light source connector 165 has a receptacle 167 , and the output light source connector 166 has a receptacle 168 . The receptacles 164, 167, 168 face upwards or downwards.

In the game machine 11, the size of the liquid crystal display 51 has increased significantly. Therefore, the difference between the width of the gaming machine 11 and the width of the liquid crystal display 51 is small. That is, the width of the liquid crystal display 51 is close to the width of the gaming machine 11 . In this case, if the receptacles 164 , 167 , 168 are oriented leftward or rightward, the cables connected to the connectors are likely to protrude from the left or right side of the liquid crystal display 51 . When the receptacles 164, 167, 168 face left or right, it is necessary to bend the cable so that it can be accommodated inside the game machine 11.例文帳に追加Bending the cable back puts a load on the connector. A load applied to the connector may affect the panel circuit 143 and the light source circuit 144 .

According to the above configuration, cables connected to the connectors are less likely to protrude from the left or right side of the liquid crystal display 51 compared to the case where the insertion ports 164, 167, 168 face left or right. Therefore, the possibility of bending the cable so as to fold it back is small. That is, there is little possibility that a load will be applied to the connector. This protects the panel circuit 143 and the light source circuit 144 . Therefore, the circuits mounted on the drive substrate 142 are protected.

(16) At least two connectors among the plurality of connectors are located on the same side of the drive board 142 . In this example, the input light source connector 165 and the output light source connector 166 are located on the fifth side 187 . This makes it easier to connect cables to two connectors positioned on the same side than when a plurality of connectors are positioned on different sides of the drive board 142 .

The projecting portion 221 contacts a portion of the component surface 161 where the panel circuit 143 and the light source circuit 144 are not mounted. According to this, when the projecting portion 221 is provided on the cover 181, between the component surface 161 and the cover 181, when the projecting portion 221 is provided on the case 91, between the component surface 161 and the case 91, A space is formed. Therefore, the panel circuit 143 and the light source circuit 144 are less likely to come into contact with the cover 181 or the case 91 even if the cover 181 is deformed by applying a load to the cover 181 . This protects the panel circuit 143 and the light source circuit 144 . Therefore, the cover 181 protects the circuits mounted on the drive board 142 . As in (13) above, the space formed between the component surface 161 and the cover 181 is maintained by the protrusion 221 coming into contact with the periphery of the connector on the drive board 142 .
