Literature 1). As shown in Fig. 13, the display device is such that the light guide plate 1' and the diffusion film 2' are substantially planar on one side, and the light transmissive film 3' (intensified brightness) having a parallel meandering shape on the other surface, The diffusion film 6' and the liquid crystal panel 4' are laminated in this order. Further, there is another proposal for a light-transmitting film having the above-described 稜鏡 shape (see Patent Document 2). As shown in Fig. 14, the optical film 60 (corresponding to the above-mentioned light-transmitting film) has a structural surface 64 and a facing surface 62. The structural surface 64 has a plurality of structures 66. The effect is such that the height of the mountain in the middle of the mountain varies continuously along the length thereof, and the depth of the valley between the mountains also continuously changes. Further, regarding the mountains and valleys of the mountains, the occurrence of the ripple (interference fringes) phenomenon of the display device is suppressed by setting the random size of the periodicity. However, in order to produce a cylindrical mold (roller) used for the optical film having the above-described 稜鏡 shape, it is produced by cutting the surface of the roller by diamond, but in order to process the mold, the diamond tool is The tool is deeply cut in and shallowly cut so that the pitch is randomly changed and the periodicity is not seen. -4- (2) (2) "1334501 'So that it changes randomly" has a very difficult problem. [Patent Document 1] Japanese Patent Laid-Open No. Hei 6-120506 (page 2, Fig. 3) [Patent Document 2] Japanese Patent Laid-Open Publication No. 2002-504698 (page 12, Fig. 5) [Summary of the Invention] In order to solve the above problems, the present invention adopts the following technical means. (1) The display device of the present invention is intended to provide a display device that is easier to manufacture than conventionally. The direction of light transmission, the repeating unit of the diffusing film and the lens is a continuous lens film portion; and the basic unit of the combination of the basic unit of light transmission and the basic unit of non-permeability is continuous image control The panel portion is laminated in this order, and the width of the basic unit of the light transmittance is set to be an integral multiple of the pitch of the repeating unit of the lens. The integer is a positive integer, that is, a natural number (1, 2). 3, 4, 5 ...) The lens film may have, for example, an array shape of mountains and valleys, and the pitch of the repeating unit is a mountain or valley size. In this display device, the basic unit of light transmittance is The width is set to -5 - (3) 1334501 is the relationship of the integral multiple of the distance between the repeating units of the lens 'the size of the mutual mutual setting' can handle the corrugation stripe, so the pitch of the mold for making the lens film portion It does not have to be random. Here, it is not a combination basic unit formed by a basic unit of light transmission and a basic unit of non-transparency, but by setting the width of the basic unit of light transmission and the lens. The relationship between the repeating units and the ripple stripe can be used to abolish the periodicity of the deviation, which is a very unexpected result.

(2) In the basic unit of combination, the basic unit of light transmittance is composed of a plurality of color filters, and a non-transparent basic unit is disposed between the plurality of color filters. The width of the basic unit of the combination is subtracted from the width of the basic unit of the total width of the non-transparent basic units of the color filters of the plurality of colors, and is set as an integer of the pitch of the repeating unit of the lens. Double the relationship. In such a configuration, a pixel is formed by a basic unit of a color filter (transparent basic unit) of a plurality of colors and a non-transparent basic unit therebetween, and the pixel is formed by the pixel. The display device, (the width of the combined basic unit, minus the total width of the non-transparent basic units of the color filters of the plurality of colors) is set as the pitch of the repeating unit of the lens. In the integer multiple relationship, the corrugation stripe can be processed, and the pitch of the mold for forming the lens portion of the lens does not necessarily need to be random. (3) In the basic unit of the combination, the basic unit of light transmittance is composed of a plurality of color filters, and a non-transparent basic unit is disposed between the plurality of color filters. The width of the color filter -6-(4)(4)1334501 color chip is set to be an integral multiple of the pitch of the repeating unit of the lens. According to this configuration, the pixels are formed by the basic unit of the color filter (the basic unit of the light transmittance) of the plurality of colors and the non-transparent basic unit between them, and the pixels are arranged in a so-called Δ arrangement. In the case of the display device formed by the pixel, the width of the color filter is set to be an integral multiple of the pitch of the repeating unit of the lens, 'the corrugation stripe can be processed, and the pitch of the mold for forming the lens film portion' is not Must be random. (4) The pitch of the repeating unit of the aforementioned lens may be formed by a combination of a plurality of divided pitches. The distance between the repeating units of the lenses of the lens film portion can be formed by a single pitch. However, when the plurality of dividing pitches are combined as described above, the lens thin film portion can be formed of a finer lens. (5) The light transmissive basic unit and the lens thin film portion are laminated at an intersection angle, and the width of the basic unit of the light transmittance is set to an integer of a distance between the repeating units of the lens across the repeating unit. Double relationship. When the distance between the repeating units of the lens is smaller than the width of the basic unit of light transmittance and is not an integral multiple, the corrugation stripe can be appropriately processed by the configuration. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings. (5) 1334501 (Embodiment 1) As shown in Figs. 1 to 6, the display device of this embodiment is a liquid crystal panel 1 having color filters (R, G, B) (see 2) and between the backlight source (cold cathode fluorescent tube 2 and mirror 3)

In order to improve the brightness, the upper diffusing film 4 and the lower diffusing film 5 are disposed with a lens thin film portion 6 having an array shape of a mountain and a valley of a vertical lattice (see FIG. 3) and a mountain having a horizontal lattice. A lens thin film portion 6 having an array shape with a valley. As shown in Fig. 4 and Fig. 6, the red pixel (R, width dr) electrode or the black mask (non-transparent basic unit) corresponding to the color filter (R, G, B) is set to dMr. Electrode or black mask (non-transparent basic unit) corresponding to green pixel (G, width dg) is set to dMg, electrode corresponding to blue pixel (B, wide db) or black mask (non-transparent basic) Unit) is set to d μ b. Then, the basic unit of light transmittance (dr + dg + db = De = Dex = Dey) formed by the color filter (R, G, B) and the non-transparent basic unit formed by the electrode or the black mask (dMr+dMg + dMb = dMx = dMy) The combined basic unit (De + dMx = D = Dx = Dy ) formed by the image control panel unit 7 (see Fig. 2, Fig. 4, and Fig. 6). The lens thin film portion 6 (see FIGS. 3 and 5) which is continuous with the repeating unit of the lens 8 having an array shape of mountains and valleys is laminated in the light transmitting direction. Further, the width of the basic unit of the light transmittance (dr + dg + db = De = Dex = Dey) is set to be an integral multiple of the distance (P) between the repeating units of the lens 8 (1 (6) (6) 13345501 times ) relationship. The aforementioned integers refer to positive integers, ie, natural numbers (1, 2 3 , 4, 5...). The pitch (p) of the repeating unit of the lens thin film portion 6 is a mountain or valley size. Specifically, in the above-mentioned combined basic unit (De + dMx = D = Dx = Dy ), the basic unit of light transmission (dr + dg + db = De = Dex = Dey) is a color of a plurality of colors (3 colors). The color filter (R, 〇, B) is formed, and the non-transparent basic units (dMr, dMg, dMb) are arranged between the color data sheets (R, G, B) of the plurality of colors. From the width of the combined basic unit (D = Dx = Dy = De + dMx), subtracting the basic unit of non-transparency between the color filters (R, G, B) of the plurality of colors (dMr, dMg, The width of the total unit of light transmission (d = Dex = Dey = dr + dg + db ) of the total width of dMb) (dMr + dMg + dMb = dMx = dMy) is set as the pitch of the repeating unit of the lens 8 (P ) an integer multiple of the relationship. Further, as shown in Fig. 5, the pitch (P) of the repeating unit of the lens 8 is further a complex lens pitch (Ρ=Σρί=Ρι+Ρ2 +...+Pk) of a combination of a plurality of divisional pitches of a specific plural. form. The widths of the respective pitches of the aforementioned Pi to Pk are not necessarily different, and may be all different. For example, can it be set to? 1=?2About 3=...=Pk. Next, the state of use of the display device of this embodiment will be described. In the display device, the width of the basic unit of light transmittance (dr + dg + db = De = Dex = Dey) is set to be an integral multiple of the pitch (P) of the repeating unit of the lens 8, by the aforementioned mutual The size setting between the 'can handle the corrugation stripe, the pitch of the mold for making the lens film portion 6 is not constant—it has the advantage of being easier to manufacture than before. -9- (7) 1334501

Here, it is not the basic unit of the combination of the basic unit of light transmission (dr + dg + db = De = Dex = De5 ) and the basic unit of non-permeability (dMr + dMg + dMb = dMx = dMy ) (D = Dx = Dy = De + dMx) "width" is set by setting the width of the "transparency basic unit (De = Dex = Dey = dr + dg + db )" and the repeating unit of "lens 8" (P The relationship 'can handle the ripple stripe, which can abolish the periodicity of the deviation that has become a problem in the past'. This is a very unexpected result. That is, for the combined basic unit of the pixel of the liquid crystal panel 1 (De + dMx = D = Dx = Dy ), the pitch (P) of the repeating unit of the lens thin film portion 6 is gradually generated by the deviation, and the ripple can be obtained. It is expected that the results will not be suitable. In addition, a combined basic unit formed by a color filter (transparent basic unit) of a plurality of colors and a non-transparent basic unit (dMr + dMg + dMb = dMx = dMy) between them (De + dMx = D = Dx = Dy) to form 1 pixel (R, G, B), for the display device formed by the pixel (R, G, B), (by combining the width of the basic unit, subtracting the complex color The width of the basic unit of the transmissive basic unit (dr + dg + db = De = Dex = Dey) is set as the pitch of the repeating unit of the lens 8 (P) The relationship of the integral multiples, whereby the corrugation stripe can be processed, and the pitch of the mold for fabricating the lens thin film portion 6 does not necessarily have the advantage of randomness. Further, the distance (P) of the repeating unit of the lens 8 of the lens thin film portion 6 may be formed by a single pitch, but it may be formed by a combination of a plurality of divided pitches (Ρ=ΣρρΡι+Ρ2+...+Pk). The lens thin film portion 6 is formed of a finer lens 8, and has an advantage of being able to enhance the fineness of -10-(8)(8)1334501 of the pixel. (Second Embodiment) The display device according to the second embodiment differs from the first embodiment in that a pixel is mainly formed by a so-called Δ arrangement. The display device (see Fig. 1) of this embodiment is a liquid crystal panel 1 (see Fig. 7) having color filters (R, G, B) and a backlight source (cold cathode fluorescent tube 2 and reflection). Between the mirrors 3), the upper diffusing film 4 and the lower diffusing film 5 are arranged to have a lens thin film portion 6 having an array shape of a vertical lattice and a valley (see FIG. 3). A lens film portion 6 having an array shape of a mountain of a horizontal lattice and a valley. Moreover, the basic unit of light transmittance (Dex = Dey) formed by the color filter (R, G, B) and the non-transparent basic unit (dMx = dMy) formed by the electrode or the black mask are formed. Combine the basic unit (D = Dex + dMx = Dey + dMy) with the continuous image control panel unit 7 (see Fig. 7), and the repeating unit of the lens 8 is a continuous lens thin film portion 6 (see Fig. 3, the quilt layer) In addition, the width of the light transmission basic unit (Dex = Dey) is set to be an integral multiple (1 time) of the distance (P) between the repeating units of the lens 8. The integer, that is, the natural number (1, 2, 3, 4, 5, ...). The pitch (P) of the repeating unit of the lens thin film portion 6 is the inter-mountain or inter-valley size, and the pitch of the repeating unit of the lens 8 ( P) can also be formed by a combination of specific plural division intervals (Ρ = Σ Pi = Pl + P2 + ._· -11 - 1334501 (9) + P k ).

Specifically, as shown in Fig. 7, among the combined basic units (D = Dex + dMx = Dey + dMy), the basic unit of translucency (Dex = Dey) is a color of a plurality of colors (3 colors). The color filters (R, G, and B) are arranged in a so-called Δ arrangement, and a non-transparent basic unit (dMx = dMy ) is disposed between the color filters (R, G' B ) of the plurality of colors, The width (De = Dex = Dey) of each of the color filters (R, G, B) is set to be an integral multiple (one time) of the pitch (P) of the repeating unit of the lens 8. Next, the embodiment will be described. The state of use of the display device. In the display device, the width of the basic unit of translucency (Dex = Dey) is set to be an integral multiple (1 time) of the pitch (P) of the repeating unit of the lens 8, by the aforementioned mutual size. It is set that the corrugated stripe can be processed, and the pitch of the mold for producing the lens thin film portion 6 does not have to be random, and has an advantage that it is easier to manufacture than ever.

Here, it is not the width of the combined basic unit (D = Dex + dMx = Dey + dMy) formed by the basic unit of translucency (Dex = Dey) and the non-transparent basic unit (dMx = dMy), but By setting the relationship between the width of the "transparency basic unit (Dex = Dey)" and the distance between the repeating units of the "lens 8" (P), the ripple stripe can be processed (can be removed due to black and white shading, monochrome, rainbow, etc.) The deterioration of the display taste caused by the occurrence of ripple streaks can abolish the periodicity of the deviation that has been a problem in the past, which is a very unexpected result. That is, for the combined basic unit of the pixel of the liquid crystal panel 1 (D = Dex + dMx = Dey + dMy), the pitch of the repeating unit of the lens film portion 6 is -12 - (10) 1334501 (P), and the ripple generated by the deviation gradually occurs. It won't happen, and you can get the right results that you can't expect.

In addition, the pixel is a combined basic unit formed by a plurality of color filters (transparent basic units) and their non-transparent basic units (dMx = dMy ) (D = Dex + dMx = Dey + dMy In the so-called Δ arrangement, by setting the relationship between the width of the color filter (R, G, B) as an integral multiple of the pitch (P) of the repeating unit of the lens 8, the corrugated stripe can be processed to produce a lens film. The spacing of the molds of the portion 6 does not have to be random. Further, the distance (P) between the repeating units of the lenses 8 of the lens thin film portion 6 can be formed by a single pitch, but is formed by a combination of plural dividing pitches (Ρ=Σρί = ρι+ρ2+...+Pk). The lens thin film portion 6 can be formed by the finer lens 8, and has an advantage that the fineness of the pixel can be further improved.

(Embodiment 3) The display device according to the third embodiment differs from the first embodiment in that the basic unit of the main light transmittance is laminated with the lens film portion at an angle of intersection 0. The display device (see Fig. 1) of this embodiment is a liquid crystal panel 1 (see Fig. 2) having color filters (R, G, B) and a backlight source (cold cathode fluorescent tube 2 and reflection). Between the mirrors 3), the upper diffusing film 4 and the lower diffusing film 5 are disposed with a lens thin film portion 6 having an array shape of a mountain and a valley of a vertical lattice (see -13- (11). 1334501 Fig. 8) A lens thin film portion 6 having an array shape of a mountain and a valley having a horizontal lattice. As shown in Fig. 4, the red pixel (R, width dr) electrode or black mask (non-transparent basic unit) corresponding to the color filter (R, G, B) is set to correspond to the green pixel. (G, width dg) electrode or black mask (non-transparent basic unit) is set to dMg, electrode corresponding to blue pixel (B, width db) or black mask (non-transparent basic unit) is set to

Then, the basic unit of light transmittance (dr + dg + db = De = Dex = Dey) formed by the color filter (R, G, B) and the non-transparent basic unit formed by the electrode or the black mask (dMr + dMg + dMb = dMx = dMy) The combined basic unit (De + dMx = D = Dx = Dy) formed by the continuous image control panel portion 7, and the repeating unit of the lens 8 is a continuous lens film portion 6, It is layered in the direction of light transmission. As shown in the lower side of Fig. 8, the lens thin film portion 6 has a cross angle of 0 and is laminated (having a slope of the ridgeline of the mountain and the valley) with respect to the basic unit of light transmittance (X-Y axis). Further, the width of the basic unit of light transmittance (De = Dex = Dey = dr + dg + db ) is set as the distance between the repeating units of the lens 8 (P) [effectively repeating the unit of the lens 8 across the repeating unit The relationship between the integer multiples (1 times) of the pitch (Pe). The aforementioned integers refer to positive integers, ie, natural numbers (1, 2, 3, 4, 5...). The pitch (Pe) of the repeating unit of the lens thin film portion 6 is a mountain or valley size. Further, as shown in Fig. 5, the effective pitch (Pe) of the repeating unit of the lens 8 may be further formed by a combination of a specific plural dividing pitch (Ρ = Σρί = ρι + ρ2 + ... + pk). -14- (12) 1334501

Specifically, in the aforementioned combined basic unit (De + dMx = D = Dx = Dy ), the basic unit of light transmission (dr + dg + db = De = Dex = Dey) is a color of a plurality of colors (3 colors). a color filter (R, G, B) is disposed, and a non-transparent basic unit (dMr, dMg, dMb) is disposed between the color filters (R, G, B) of the plurality of colors. Substituting the non-transparent basic units of the color filters (R, G ' B ) of the plurality of colors (dMr, dMg, dMb) from the width of the combined basic unit (De + dMx = D = Dx = Dy) The width of the total unit of light transmittance (dr + dg + db = De = Dex = Dey) of the total width (dMr + dMg + dMb = dMx = dMy) is set as the effective pitch of the repeating unit of the lens 8 (Pe ) The integer multiple (1 times) relationship. Next, the state of use of the display device of this embodiment will be described. In this display device, the width of the basic unit of light transmittance (dr + dg + db = De = Dex = Dey) is set as an integral multiple (equal multiple) of the effective pitch (Pe) of the repeating unit of the lens 8. By setting the dimensions of the above, the corrugated stripe can be processed, and the pitch of the mold for forming the lens thin film portion 6 does not have to be random, and has an advantage that it is easier to manufacture than ever. Here, it is not the combined basic unit of the basic unit of light transmission (dr + dg + db = De = Dex = Dey ) and the basic unit of non-permeability (dMr + d\lg + dMb = dMx = dMy) (De + dMx = D = Dx = Dy )", but by setting the width of the "transparency basic unit (dr + dg + db = De = Dex = Dey)" and the repeating unit of "lens 8" The pitch (Pe) relationship can handle the ripple stripe and can abolish the periodicity of the deviation that has been a problem in the past. -15- (13) 1334501 This is a very unexpected result. That is, for the combined basic unit of the pixel of the liquid crystal panel 1 (De + dMx = D = Dx = Dy ), the ripple generated by the deviation of the effective pitch (Pe) of the repeating unit of the lens thin film portion 6 does not occur, and it is possible to obtain Even the expected results are not suitable.

In addition, a combined basic unit formed by a color filter (transparent basic unit) of a plurality of colors and a non-transparent basic unit (dMr + dMg + dMb = dMx = dMy) between them (De + dMx = D = Dx = Dy) to form 1 pixel (R, G, B), for the display device formed by the pixel (R, G, B), (by combining the width of the basic unit, subtracting the complex color The width of the basic unit of the light transmission basic unit (dr + dg + db = De = Dex = Dey) is set as the effective pitch of the repeating unit of the lens 8 (Pe By the relationship of an integral multiple, the corrugation stripe can be processed, and the pitch of the mold for fabricating the lens thin film portion 6 does not necessarily have to be random. In addition, the basic unit of light transmission (dr + dg + db = De = Dex = Dey) and the combined basic unit (De + dMx = D = Dx = Dy) have a cross angle of 0 and are layered (to make mountains and valleys The ridge line has a slope), and the width of the basic unit of the light transmittance (dr + dg + db = De = Dex = Dey ) is set to be the lens 8 which traverses the aforementioned repeating unit (De + dMx = D = Dx = Dy) The relationship between the integer multiple (1 times) of the effective pitch (Pe) of the heavy unit, the pitch (P) of the repeating unit of the lens 8 is larger than the basic unit of the light transmittance (dr + dg + db = De = Dex = Dey) When the relationship is small and not an integer multiple, by making such a configuration, it is possible to appropriately handle the ripple stripe. Further, the distance between the repeating units of the lens 8 of the lens thin film portion 6 (P) -16 - (14) (14) 1334501 ' can be formed by a single pitch, but by the combination of the plural divided pitches (Ρ=Σρί = Ρι+ρ2+...+Pk) is formed so that the lens thin film portion 6 can be formed by the finer lens 8, which has the advantage of further improving the fineness of the pixel. [Embodiment 1] As shown in Fig. 2, for the liquid crystal panel of the X-Y matrix electrode structure, R, G, and B3 points are set to 1 pixel. Then, in the X-axis direction, the aforementioned pixels are sequentially set to the first, second, and third... i. "m. In the Y-axis direction, the first few pixels are sequentially set to the first, second, third, ..., j. ... η. Fig. 6 shows the relationship between R, G, the point and the pixel formed by the stripe arrangement, and the relationship between the dot size, the pixel size, the electrode or the black mask width. In the sixth (1) In the striped color filter liquid crystal panel of the figure, the widths of the color filters (R, G, Β) are set to dr, dg, and db, and the color filters (R, G, B) are used. The width of each of the electrodes or the black mask is set to dMr, dMg, and dMb, and the width of the one pixel formed by this is set to Dx (X-axis direction) and Dy (Y-axis direction) (=D, Refer to Figure 2 and Figure 4).

In the 6th (2) (3) (4) diagram, it is shown that the widths dr, dg, and db of the color filter (R, G, B) are collected for the r, g, and B points. The basic unit of light (dr + dg + db = De = Dex = Dey), and the width dMr, dMg, dMb of the electrode or black mask are integrated into the basic unit of non-permeability (dMr + dMg + dMb = dMx = dMy ) idea. Moreover, the basic unit of light transmission by the stroke of the color filter (R, G, B) (dr + dg + db = -17- (15) 1334501

De = Dex = Dey ), and the basic unit of impermeability (dMr+dMg + dMb = dMx = dMy) of the stroke of the electrode or black mask to form the combined basic unit ( De + dMx = D = Dx = Dy) 1 pixel.

As shown in Fig. 5, the division pitch of one pitch of the lens thin film portion of the crucible is set to Pi = Pi, P2, ... Pk (as in Fig. 8, when the lattice counter electrode is inclined, the effective pitch is pei) . The transmittance of the liquid crystal panel is set to Tp, and the light intensity of the lens thin film portion is set to U. The Τρ is set as a rectangular period function of the transmittance of the electrode portion or the black mask portion or the transmittance of the color filter portion α, and U is simulated as a trigonometric function of the light intensity coefficient /3. As shown in Fig. 4, the pixel numbers of the liquid crystal panel are set to Νρ = 1, 2, 3, .... In addition, when the rectangular window function of the liquid crystal panel is Τρ and the amount of shift of the ridge line of the lens thin film portion in the X-axis direction is (y), it is expressed by the following function.

If the ratio of each pixel to the total average of B(i, j) is expressed as a percentage, it is expressed by the following equation. [Equation 6] (5) [Embodiment 2] The transmittance α of the transmissive portion of the pixel of the liquid crystal panel and the emission optical coefficient/5 of the prism lens portion were normalized to 1. The size of one pixel (DX: combined basic unit, Dex: basic unit of light transmittance, dM: basic unit of non-transparency) was set as in Examples 1 to 4 of Table 1. The division pitch (Pi = Pi, P2, ..., Pk, k = 6) of the composite lens (P) was set as in the first to fourth embodiments of Table 1, and the ridgeline of the valley of the lens was arranged in parallel with the Y-axis. Regarding the X-axis direction, the amount of movement (deviation amount) of 20%, 50%, and 80% of the electrode width dM is λ , ( y ) ' λ 2 (y) ' λ 3 ( y ), respectively.

On the other hand, as in the first and third embodiments of Table 1, in the case of Dex # P, the unevenness of the liquid crystal panel and the lens lattice is uneven, that is, the ripple is 3.3% due to the difference between D ex and P. . Further, the size of the shading of the generated ripple stripe is independent of the amount of movement (deviation amount) λ (y) in the X-axis direction. That is, in the lens thin film portion, the movement of the liquid crystal panel in the X-axis direction does not affect the size of the ripple. Figures 7 through 10 show the results of Examples 1, 2, 3, and 4 in Table 1 above. Individual λ (y) is set to λ 2 ( y ). Even in any combination, if it is set to the following formula, the ripple generation can be released.

In the case of the Δ arrangement - 21 - (19) 1334501 'The width (1 color) of the color filters of the respective colors of R, G, and B (three colors) is set to Dex, respectively, if the above formula (6) is satisfied (Dex When P = ."), the ripple stripe can be removed. In this case, Dex (transparency basic unit: color filter of 1 color) + dMx (non-transparent basic unit: electrode between the above-mentioned color filters, etc.) = Dey + dMy = D (combination basic unit) ) relationship. In addition, when the stripe is arranged as shown in Fig. 4, the width (one color) of each color filter is set to Dex, respectively, as in the Δ arrangement, if (6) is satisfied.

When the formula (Dex = P=···), the ripple stripe can be released. In this case, it also satisfies Dex (transparency basic unit: color filter of 1 color) + dMx (non-transparent basic unit: electrode between the above-mentioned color filters, etc.) = Dey + dMy = D (combination basic Unit) relationship. [Example 4] When the pitch (P) of the lens thin film portion is smaller than the basic unit of light transmittance (Dex), that is, when Dex>P, as shown in Fig. 8, the Y axis of the liquid crystal panel is as follows ( 8) As shown in the figure, the ridgeline of the mountain or valley of the lens has a slope of 0, and for the lens pitch of the actual lens film portion (Ρ = Ρι + Ρ2 + ρ3...Pk), the effective lens is traversed on the X-axis. The pitch (Pe = Pel + Pe2 + Pe3 ... Pek), when the width Dex of the basic unit of the light transmittance is set to be an integral multiple of the effective pitch (pe) of the repeating unit of the lens 8, the corrugation can be released. -22- (20) (20) 1334551 [Math 8]

Dex=Pe = YJPei 0 =1,2· A:) ( 7 ) ί=1 θ =±cos~'(P/DJ (8) For example, for the embodiment shown in Table 1, by the design of the liquid crystal panel When 〇εχ=185μηη, when the lens film has a slope of 0 = ±8.4 degrees for the x-axis, the equation (7) is satisfied, and the ripple can be released. Thus, the electrode of the liquid crystal panel The arrangement can be optimally adjusted by arranging the ridgeline of the mountain or valley of the lens thin film portion with a slope of 0. Thus, the basic unit of light transmittance and the lens thin film portion 6 are stacked at an angle of 0 to be laminated. When the distance between the repeating units of the lenses is smaller than the width Dex of the basic unit of the light transmittance, and the relationship is not an integral multiple, the corrugation stripe can be appropriately treated. [Effect of the invention] The pitch of the mold for forming the lens thin film portion is not It is necessary to have a randomness, and it is possible to provide a display device that is easier to manufacture than ever. [Industrial use possibility] The pitch of the mold for producing the lens film portion does not have to be random, and it is easier to produce than the conventional one.
